Sending public key is very wrong especially, if it is a master public key, sending private key will only lead to scam, sending email can only lead to more (email) phishing attack. Click on any link is dangerous, it can be malware line, it can be an unsecure link that can steal information from someone. People that are very careful of their privacy will not fall for this scam, but most people in the world do not even know there is anything called online privacy as I was did not.

You can read check this thread, you will see it helpful. You can also move this to 'bitcoin technical support'

As e be for my side, I accept the happy new month, but to dey greet for independent day, I no accept ham at all. At 60th anniversary, Naija dey inside dept, people dey suffer, leaders born in Naija have citizenship of another country like USA and UK, inflation rising, poverty dey increase. I no know why we dey celebrate today when things dey fall apart.

Quantum computing is still in it early stage, there is no such computer that is advanced in a way to break the ECDSA algorithm of bitcoin as of now. Quantum comouting is only a threat to the future of bitcoin, because in decades to come, there will be advanced and more sophisticated quantum computers that will be able to penetrate bitcoin ECDSA algorithm. But, it is only a panic for people that do not know much about bitcoin, it is nothing to bitcoin developers because quantum resistant soft fork will be created.

It takes bitcoin developers little stress to have a soft fork to create a new address that will be 100% resistant to quantum computer, imo, it will be the best alternative.

Normally, people can have the thinking that the app can track them to their identity, that it is very possible for medical emergency support to come to them for medical attention and take them to isolation center without any notice before. Many people like to just keep calm even when they are feeling symptoms, and of which is very bad. The app only works on their phone without them being tracked, but their phone can be tracked to easily identify them in public, so this can make them not to report the app anything.

But like Juggy777 have commented, it is for their own good, to help reduce the spread of the virus, they have to cooperate than not doing anything. All the food restaurants also should not take it lenient by making use of the QR codes, it costs them nothing than seconds to make use of that for each person.

@Jet Cash, I get your point, you are right. But, the government are only trying means to reduce or cease the spread of the virus. Like you that believe in natural immunity, I think this is another great idea, after using nose mask, hand sanitizer, and soap at home. I like this invention if truly it is working. But, like you said, people are not cooporating , but at least, it is a good thing and it is a way to prevent the disease if people are cooperating

What makes me surprised is that they have been existing since 2019 till now, or has the site long ago be partially taken down? Because if not take down, many people would have been scammed. Normally, exchanges can not ask for any ransom, we all know who can ask for ransom, which are scammers, it is truly a scam site. Making proper research about an exchange before registering on the exchange is very essential, but most of the scam exchange can use free giveaways to lure victims to send bitcoin or any other crypto into the exchange. It is great that people have been warned now that the exchange is a scam exchange. Scammers are just wicked, after freezing (scam 1) someone's account (scam 1), they still ask the victim to pay for ransom (scam 2).

Brainboss have answered the main part of the question, but there is need to also know that on Paxful, individual traders (buyers and sellers) are setting their price, not the exchange that is setting it. So, for example, if bitcoin is at the price of $10000, there are buyers that will set it at varying prices and also sellers setting it at varying prices. So, using Paxful as an example does not matter in this case. Assuming, if it is the exchange that set the price, it would have been a good example. I have ones used Paxful before, even the price the traders set can be changed by the traders upon dialogue after series of negotiations that both parties agreed upon. The price set by the traders may not actually be the price they will buy or sell.

There was a day I want to sell bitcoin on Paxful, the buyer told me to reduce around $2.5 in the local currency that he can not pay more than that. I was in haste, and I had to sell it, it happens like that on paxful, the buyer or the seller can be in haste to trade. So, saying they buy bitcoin in loss is not actually what is happening if you have used the exchange before.

I still do not get the point, when the txid is enough to know the transaction is actually from you and confirmed. As you are advised above, it will be good to send them the txid of the confirmed transaction. Maybe the wallet issuer they are requesting for is the txid. And better still, send them your wallet address along, in case.

With what I have heard before, this forum was created to share knowledge among bitcoin users, which means this forum was initially filled with bitcoin developers and investors. They asked questions and get answers to it. I really like the creator of bitcoin, Satoshi Nakamoto, after creating bitcoin, he created this forum, not because he felt like but he knew this forum will help people because bitcoin is handled digitally, this forum is another awareness that bitcoin is decentralized, owned and handled by individuals. And taking responsibility of their asset (bitcoin) is very paramount. Which means his intention of creating this forum is to tackle all issues related to bitcoin and later other cryptocurrencies. I wonder while people are now investing on bitcoin and did not know about this forum, centralization only make people ignorant.

This means people should be aware of bitcoin and other cryptocurrencies as been decentralized, I expect people that are having bitcoin and/or anyother cryptocurrencies  to be on this forum, not because of campaign but to gain on how to avoid scam, to know what bitcoin and other cryptocurrencies actually are. It will not be surprising that some people only buy bitcoin and other cryptocurrencies but they did not know it is decentralized. This problem is caused by centralization in many aspects.

Centralization makes people weak, but they did not know, all what governments want to do is to centralized the world, and centrization is very partial, helping the riches but affecting the less privileges, I can see a very rich man that move millions of dollars out side my country, but very difficult for people like me to move $110 monthly, because the international spending now in my country is $100 in maximum while using credit cards. We are not able to control our money the way we want because it is centralized, but this does not apply to politicians and rich people. And yet, the fiat can be used to launder money or finance terrorism.

The governments are only support centralized exchanges now because they are able to regulate it, but over 90 exchanges have been hacked since 2012 till now. Anything centralized is faulty at one side while decentralization is an alternative to let people recognize the fault. But, people are not still aware of this decentralization. People need to be aware of what decentralization is all about, but governments do not want it, and there are still 90% of money laundering and terrorism financing in the centralized system. 

The issue of scam needs to be addressed generally although, but as centralization makes people weak, they only focus on governments to protect their money for them, that is why some people are using centralized exchanges that are often hacked, that it is regulated by the governments, unknown to them that they can have their private key offline and protect their assets with high level of privacy.

It is my pleasure to be interviewed

---

1. When and why did you become interested in cryptocurrencies?
I know about cryptocurrencies in late last year, 2019. Seemed too late but nobody knows what the future holds. I am a university graduate since 2016 but no job and underemployed, the rate of employment in my country is very high and leaving us to be so underemployed and suffering. The first money I earned in my life with ease was bitcoin, that was how bitcoin really helped and attracted me. I was able to participate in some bounties and earn (although we need to be careful of bounties because some can be scam while many can lead to scam), that really encouraged me to even join this forum in March, 2020. And now I am earning from this forum. The fact is, the money I have earned in crypto in less than a year is for more than the money I have earned in fiat for five years. The reason I was interested in cryptocurrencies is because I want to earn money and make life easy for myself. And it is fulfilling.


2. When and why did you buy your first bitcoin?
God so helped me to be a fast learner. Cryptocurrencies have much opportunities in ways you can work for it and earn it. All the bitcoin I have today, I did not buy it, I earned it. I prefer the earning part. But, if I am employed today, I am ready to have some of my savings in bitcoin which will be the first time I will be buying bitcoin.

3. How did you get on the forum?
It was a long story, but let me make it short. A scammer messaged me on facebook messenger posing as a prostitute, sending me nude pictures, depicting herself to be studying one course (forgotten the course) in University of Mississippi, two days after we met, she told me to send her $200 worth of bitcoin or google play gift card that she wants to use the money to buy tools for her school assignment. I believed it is a scam, and I did not send her anything. With that, I noticed bitcoin can serve as money purpose (I have known bitcoin since 2013 but not knowing it serves money purpose, what a novice). I later browsed about bitcoin and started to know what bitcoin is, and from there, I know about cryptocurrencies in general. I later browsed how to earn bitcoin online. I saw faucets, pay to click sites, trading, hodling and bitcointalk signature campaigns. I tried all, and that got me into this forum.

4.1. What prevents mass adoption of cryptocurrencies?
Normally, cryptocurrencies  have mass adoption already, but it supposed to have been more adopted if not for certain reasons, the reason are many but I will only talk about the most important ones. They are:

Ignorance
Permit me to make use of this scenario, assuming people can have their fiat with them, and they can be able to use the fiat the way they like, send it to families and friends abroad and nearby, make use of it for transaction purposes, having it with them without any thief coming by, and all without any third party. I believe with this, people will not even think of bank which has later become so centralized. But, all these benefits, cryptocurrencies can give. Which means, cryptocurrencies can serve the initial purposes of money.

Let us take bitcoin as an example, you can have your own wallet that nobody can control it but you, having privacy and not depending on any third party. But, people do not know about this, people are ignorant about bitcoin while some are thinking it is a scam, while some are thinking it is a ponzi scheme, while some even do not know that bitcoin has intrinsic value and can be regarded as money. If people can truly really know what bitcoin and legit cryptocurrencies are, there will be more increase in adoption rate of bitcoin and altcoins.

Governmental laws and restrictions
Also, governmental rules and regulation are another reasons, countries in the world have not yet legalized cryptocurrencies to be taught in schools, while some countries strictly ban cryptocurrencies. In such countries, some people can still find a way to buy and store cryptocurrencies but the adoption rate in such countries are not as high as in the countries that legalize it. If governments of such countries can legalize cryptocurrencies, the rate of adoption will increase, also, if cryptocurrencies are taught in schools, people will not be ignorant about it and know how important they are as a means of decentralization leading to increase in crypto adoption.

Unemployment, poverty and lack of investment capital
Other reasons which I will not go deeper into which are connected to the reasons cryptocurrencies have not been adopted to its fullest are unemployment, poverty and lack of funds. Some people even know about cryptocurrencies but they lack investment capital, this is common in countries that are underdeveloped, and that is why countries that are rich are more investing and trading cryptocurrencies than countries that are less rich or poor.

4.2. How do you think mass advertising of gambling projects has a positive effect on the development of the forum or harms the community?
If betting company bring their campaigns here, I do not see anything bad, some members of the forum will benefit from the campaign they offer. I play most of my bets on bet365 before which do not support bitcoin and other cryptocurrencies, but this forum changed that, fiats transaction fee is too high, and there are too much regulation in a way the governments are controlling our funds and restricting us to pay for many international transactions due to inflation and money declination, unlike bitcoin and other cryptocurrencies. With this, many people like me have diverted away from betting with fiats but now betting with bitcoin and other cryptocurrencies which is a way best, many of the companies have campaigns here which helps the forum to moving forward. Although, I bet, but I should still say people should be careful while betting, they should not use the money they can not afford to lose to bet, so that betting will be fun.

4.3. How do you consider whether 2-3 years of experience in cryptocurrency is enough to successfully invest or does an investor need to receive special education?
People are different, our assimilation rate are also not the same. I was able to know about what to do and how to successfully invest on some cryptocurrencies like bitcoin, ether, litecoin and dash earlier. I also know how they can be risky and what to do to make to gain from my investment plans. But, there are some people that will still need to be taught about this, while some even need long term experience, but 2-3 years is too long for such experience, at list 3-6 months is okay which I even still consider too long. Checking the prices of this coins technically using charts will really help than waiting too long, in my opinion.

5. What do you think of the current Merit system and signature campaigns? Do they harm the forum?
I do not think anyone that did not contribute to an organization should earn from such organization, the merit system has helped us to easily know people that are contributing quality posts to Bitcointalk forum, the quality post is the determinant of the forum quality. Bitcointalk is a quality forum today than what I heard has happened in the past when a single person will have more than 5 accounts. I think it will even be a norm before to have many accounts as it is tempting, but the merit system makes it difficult for a single person to build two accounts. Merit system discourage one person to use two or more accounts to join a signature campaign, merit system makes this hard. I consider the merit system to be a decentralized non-kyc means of solving what kyc is needed for.

About signature campaigns, they are helping the forum very well, it is one of the reasons people are getting to know this forum, if you checked how I know this forum, it was through search engine about how to earn bitcoin, it was the signature campaign that was referred to on this forum, not this forum itself, I so much remembered. So, many people are here to earn but ready to contribute by helping people to know about cryptocurrencies and contributing to knowledge and solving people's questions that are asked on the forum.

Quality post is a prequisite to merit which is a prequisite to joining signature campaign which is a requisite to making more people joining the forum which is a requisite to the wellness of the forum. This is a win to win called positive feedback mechanism which indicate how merit system and signature campaigns play good roles in the progress of this forum.

6. The most useful forum topic? Most helpful users?
I can not say a topic is most useful because there are many useful topics, there are some I can not forget like 'how to consolisldate your total inputs' and some technical questions that I might not find answers to if not of the forum. Also, topics about scam, ways to avoid scam is so much useful for me, the forum makes me realize that not all should the government handle, we have our own parts to play to secure ourselves from scammers. About users that I have gained from, they are many, it will be biased to mention some and leave some not mentioned.

7. 3 things you would implement on the forum?
I will not say these are implementations, but they are what can make the forum move forward, if I achieve in life, and I have any business I want to advertize, I can bring my campaign here, and also looked for means to make the forum more attractive for people. I will like free giveaways on the forum like contests and likes. We have to attract people to join this forum to let them know about decentralization, how it is important and how to avoid scam which are the main aims of this forum.


8. Do you trade on exchanges or invest in projects?
There have been over 90 exchange hacked since 2011, the hacking rates was higher in 2017 till now, even some people do not know the binance exchange was hacked in 2019, there have been many people that have lost money to centralized exchanges which makes trading easy and flexible and mostly used by people. I traded on exchange when I was learning how to trade, day trading was a great loss for me, but I use a very low amount of money, in a way if the exchange I am using is hacked, I will not have nothing to lose than $50. I do not invest on any project, I can lose while many of the project can results to loss, although many people have been lucky, but I am not the type, I like to invest in what I know about like bitcoin. The only thing I am doing now is swing trading (hodling in a range of 2 weeks to 6 months), and I hodl bitcoin as well. I have my seed phrase which means I have my private keys to my bitcoins, rather than using centralized exchanges the are often hacked.

9. Tell a story about your big profit or big loss?
This should be a long story but I will make it short, my biggest profits and losses are in gambling, trading (day trading to be specific) and on shady things on exchanges.

There was a time I converted bitcoin into a shitcoin, but all I noticed was that it resulted into a loss for me immediately, instead, I should have used low value coin in price like doge for the conversion or use tether which assumes the worth of $1, but I used bitcoin directly for the trade. I traded $50 but the result after the trade was less than $0.005. It was a big loss for me.

I remember when I fomo, I bought doge at a price of $0.0048 but less than a day, the coin dropped less than $0.0035 and still dropped further.

I included gambling not because I really had losses, actually it was not much, I am disciplined to use the amount I can afford to lose and not think about it, but I have not gained from betting before and it has been what I do not like. Although, my discipline makes it fun for me as well.

The last I can remember for now was when I bought a coin, I invested the coin with 10% daily profit, I was so happy to buy the coin but I later lose a lot. I bought $50 worth of the coin and within 30 days, the coin dumped more than I expected, with the 10% daily profit I have gained, I cashed out $18. Which means I still lost $32.

10. What do you think about the DEFI ecosystem?
I have seen DeFi like the 2017 ICO but a little bit different, and it is not surprising that many of the projects that were white listed pulled an exit scam. The CEO of Myetherwallet even says DeFi is too noisy saying many investors have gained while many have lost investment capital in 2020. How about the exit scam that tron legitimized, tron community was blaming just foundation for whitlisting the token that pulled and exit scam pocketing about $2 million in TRX tokens, there have been many DeFi projects that significantly increased in price in just few days but deceased back abruptly, the last I heard of now is a token called 'strong'. As some decreased in price, it can take time for them to rise back, or even maybe not rise back to the price expected by some investors in years, thereby the investors losing. I like to embrace what I have known about, I am not a fan of DeFi, I prefer bitcoin and other strong cryptocurrencies, rather than a projects that seemed more like ICOs in term of making profit or loss.

11. Is your anonymity a vital necessity or precaution?
I wish I can be anonymous but truly it is very difficult for me, but I still maintain some privacies which is now my alternative, there are some part of me people really know while there should be some parts they do not have to know.

12. The last cryptocurrency book you read?
I read using search engines but not through google search engine that are promoting scam activities by advertising scam ads, I remember when I started knowing about bitcoin, I make use of 99bitcoins and investopedia, but I read a lot more using DuckDuckGo search engine. But, there are times I make use of mastering bitcoin which really helped me especially to truly know what bitcoin wallet actually is and also to know a lot more about bitcoin.

13. Advise 3 cryptocurrencies/tokens for investment in the next 1-2 years?
There are over 5000 cryptocurrencies on coinmarketcap, even there are over 7000 on coingecko, there could be over 10000 cryptocurrencies in the world in which some are not yet listed on such sites but only certain exchanges. Most of the coins are subjected to manipulates, pumps and dumps (wolves of wall streets). There are many you will invest today and lose tomorrow, I have only seen top listed coin according to their marketcap to be the best to invest on because the higher the marketcap the lesser will be the manipulations. Bitcoin have been the first always which people can invest on, while I will take ether and litecoin as the second and third respectively.

14. How much will Bitcoin cost at the end of 2020
Nobody knows what the price can be, anything can happen that can let the price to decrease, but if nothing of such happen, let us still expect $15000, I guess. I like the support the price is showing at $10000, which is an strong evidence that it is likely bitcoin price will not drop for now, even if it decreases further below $10000, after the storm will be the calm, the price will still likely increase back above $10000. Imo, at the end of this year, I am expecting bitcoin to be within a range of $10000 to $15000 or to have increase above $15000.

15. P.S. (Optional)
I will like to let us be encouraging people about what bitcoin is, how it is decentralized, how it serves the initial purpose of money and how has been great alternative time centralized money. Let us also be educating people around us about scam, what we tell people about scam today and what they know through us can save millions from being scammed.

Kyc is extremely dangerous, possibly the phishing attack is from one of the sites you did verification and included your email, be it legit site or not. This type of email should be ignored, even, if the email is legit, so far you do not authorized for it, it should still be ignored. This is a very common scam now, but many people are still being victims. This is one of the harms of centralization that scammers do take advantage of. Many scams are occurring in the decentralized systems because of centralization.

If one of the private keys is lost, it is catastrophic. For example, if you set 2 signatures, that means you will have 2 cosigners or more. If you have 2 cosigners, that means you need the two private keys to be signing transactions. Assuming you lost one of the private keys and you need it to be able to sign a transaction, that means the wallet is useless if you can not get the backup. You will need the two private keys for each transactions you are making. Many wallets are not accessible by owners because of too tight means of accessing their wallets.

First, know that if bitcoin Elliptic Curve Digital Signature Algorithm or ECDSA can be over-riden by Quantum Computers, multisig wallets will also be susceptible, it is done in a way that addresses can be used to generate the private key belonging to the addresses. But, know that this will not happen. Bitcoin algorithm will be by then advanced in a way advanced quantum computing will not be able to compromize.

Second, if you are protecting your bitcoin, you should let it be in a way that you will not lose your access to you or keys, if you only accessing bitcoin with multisig, that means you will have two or more devices, that means you will have to protect all the private keys. Multisig are designed to be used by companies in a way two or more people will be able to sign transactions. But, for one person, I will not recommend it.

If you have only one private key, and it is stored offline, nobody can brute-force the key, not possible. Hardware wallets provided you a mean your private keys can be stored offline. This means your private keys can not be revealed to hackers, but, we all still know that we still have to take security essential because anything can still happen. Making sure your device you use to operate the hardware wallet is not having any malware, protecting the device is another thing to have in mind.

Security is not about using multisig wallet or regular wallet, it is about what you know about how to avoid hackers, the way hackers penetrate is easy, but only experts knows how to avoid, if we know how to avoid, that is enough. Be it multisig or regular wallet.

Plagiarism and spamming belongs to the same illegitimate categories, it is usually done by people that do not want to learn but to copy and paste other peoples contents. Some people even do not know where the rules are, all they want to do is to post, some people are clearly seeing the link to the rules but they do not want to read it at all until they make mistake. But, normally, why are newbies like copying, this is wrong, and at least, there is an option to include the link, but they will still not. I too will advise them to read the rules, and they should not copy and paste, even if it a a single line they copied from another source, the link must be added to it, they should go on the forum easy, it is not only about posting, but also about posting quality contents that are authentic and meritable.

The best newbies can do is to first learn, not only thinking about the merit, but learning how merited posts are, with time, they will get to know the forum better, instead of rushing. If they know about the forum to and extent, they will see the forum so interesting. But, the start may not be easy as they have to learn a lot rather than plagiarizing and spamming what could get them into trouble all because they want to earn merits. If they learn, merit will come there ways.

This is a forum, it has rules we should follow, so not to fall out of the forum norms and ways of posting. In short, we have posting etiquettes. Where there are no laws, there are no sins, people can do the way they want, but, this forum is not like that. This forum condone no such mistake, I mean plagiarism and spamming. For new users that spam on this forum, ones it is evident from another source, the person will be banned, and it will be a permanent ban.

For example, even if an organization wants to employe you, they will have to first interview you, before the interview, you would have browsed about the company, knowing more about them, so that you will not failed the interview. This is just like reading the forum rules, and it is not only about reading the rules, it is also about abiding to it. I do not expect people to do what could put them in trouble, while some people still like doing it by disobeying.

There are some mistakes that worth correction, some newbies can even still be adamant to the correction, arguing and even implying ranked members are the ones that are not correct. Even after all such things, ranked members still do correct newbies all the time on this this, especially because of their newbie misconception about bitcoin and other cryptocurrencies. So, implying ranked members not correcting newbies, this is wrong, they always do correct newbies very well. But, not to the extent newbies are againsting the rules of the forum which can get them permanent ban. It is all over everywhere, not only this forum, that spamming and plagiarism they do not condone.

Another scenerio, if you are in an examination hall, and you are copying your fellow students, if you are seen by a supervisor, it can also get you in trouble that can result to the person to fail the example or carry the course over.  Do just obey the rules of the forum is a requisite to you not getting banned.

Yes, and that is how it has been on exchanges that were hacked generally thus far. I read from a news today that vast majority of  exchanges are using hot wallets. Why won't the exchanges be hacked so far they are making use of online wallet to secure funds of thousands of users.

Nothing edited than the misspelled bithump exchange. Try to read the news using the links I provided. Although, you are right by faulting the two users that was not later linked to the hack, it was due to their fault through phishing attack, and all explained in my write up. But what about the third person? Over $27,000 was stolen but only compensated with $5000, that was my point. Why did you think he was compensated if the fault was not from bithump exchange? It was actually from the 2017 bithumb hack. I hope you know majority of the exchanges are using hot wallets to save the funds of thousands of users?

It was actually a phishing attack with only two of the victims, the third person's attack was linked to 2017 Bithumb exchange hack.

Non of them recovered their lost funds, only one of them was compensated with $5000 after claiming to have lost $27,200. Check the link below.

Two of the victims were investigatesd faulty of their attacks. But the third person was compensated.


But that aside, normally, exchanges are too vulnerable to attacks, that is why Bytbit CEO even says most crypto exchanges are vulnerable by design that he isn’t surprised attacks happen on crypto exchanges. A statement we all know that is true.
https://cointelegraph.com/news/most-crypto-exchanges-are-vulnerable-by-design-says-bybit-ceo

To be sincere, I can not believe this until I read on news about a victim that lost $401,000 due to the hack of the exchange he his using. Although, the hack could be due to the his fault, but reported by him to be as a result of the 2017 Bithump exchange hack. This was a shock and surprise on my side that how can someone keep such high amount of funds on an exchange, even custodial wallet is not perfect for such amount, neither are any hot wallet perfect for the purpose. Cold storage like hardware wallets like Trezor and Ledger nano should be perfect, which should also be carefully handled.

Previously, a number of other Bithumb users had attempted to hold the exchange accountable for losses stemming from the data breach. A judge ruled on September 3, however, to dismiss two out of the three claims — for $126,000 and $38,000. A third user was awarded $5000 (significantly less than their losses) when the court found that Bithumb was partially responsible in that particular case.

The fact still hold, that not your private key, not your coin. Even, the person that was seen to be hacked due to Bithump exchange hack was reportedly given an amount that is significantly lesser than his investment on the exchange. This would have not happened if these investors are using hardware wallet, in which they will have keys to control the coins themselves.

Bitcoin and other cryptocurrencies makes payment more easy, and bitcoin specifically brough decentralization to the world, it has been very a good thing that has been embraced by people in the world, that is why the rate of adoption has been always increasing. If I like, I can make use of bitcoin to pay people from abroad, instead of the restrictions caused by governmental laws.

This topic should be focused on fiats and not cryptocurrencies. I still know how many football players do evade tax not to talk of politicians/politicos. I have thought of it and looked for ways people can evade tax, if a company is in a country, governments can do it in a way the company and its workers will pay tax, even if they pay workers with bitcoin. That should not be an excuse but the governments to be blamed if they are not taking necessary actions to make sure the companies in their country are not evading tax. If tax can happen in crypto, that means it is happening most in fiat in such country.

About money laundering, I hope you know what united states SEC addresses about this after many investigation they make, although, it is very possible money laundering to be common in cryptocurrencies later, but as of now, money laundering in cryptocurrencies is nothing to be compared to money laundering in fiats. I hope you read on news the recent $2 trillion malicious activities that has been existing for years in top banks of the world.

About ransom, this is common even before the creation of bitcoin in 2009, in a way hackers encrypt a company or someone's data and request for random. The ransom can be collected in cryptocurrencies but also can be collected in fiat which is even the origin. How about the criminal cases that someone can be stolen, or many other things like that, that the criminals will demand for ransom in fiats which is even common in that case.

About ponzi, the first ponzi I know in my life is MMM, it is a fiat ponzi, what is the origin of ponzi, is it not fiats? It is. I understand your points, but we have to let people know that these are mostly happening while using fiats. Bitcoin and legit cryptocurrencies are not scam, it is people that are the real scam, and they make use of fiats more than cryptocurrencies for their malacious acrivities. I expect this article to be how to avoid all these rather than depicting cryptocurrencies this way. 

Nobody can predict the price of bitcoin, but in my opinion, some days before halving and after halving, we have noticed bitcoin was more resistant to decrease below $8000. Possibly, it can happen in a way the price of bitcoin may not be less than $10000 throughout this year, I think the fall has already happened in March. There may not be any significant increase as well but I think we do not have to be panic about the price. Bitcoin price this year can not be lesser than that of March, $3850 which was even $3600 on some exchanges.

The first bitcoin price decline I experienced was the one of this year.
