Imo, if an account can be opened even without kyc, it will even be the best. There are many legit wallets and exchanges that can be used for hodling and trading respectively, to go for such will be good. In this way, there will be more privacy. But at times, there can be no option, especially while dealing with non-crypto related accounts, and forum accounts, in this case, the first thing to come to mind is to use 2FA, having the 2FA app on another device is advisable, the password created should be a very complex one that can not be easy to guess or brute force, and also using a new/different email which with strong password is recommended.

After all these are considered, care must still be taking because unsecure broswing can still lead to careless leak of someone's personal information.

Personally, I do not consider this act as a scam. First of all, the investor knew it already that the value of those coins are not stable, just like bitcoin. The only difference is that most of the coins on Investbox are shitcoins (they will lose their value in no time), specially if it is offering that high daily return.
I see this to be scam. In conjunction with shitcoins, they are scam. Shitcoins are the ones having high yield investment rates, but still result into losses for most investors as their prices getting decreased more than the investment profit. Especially newbies are the ones losing much.

4. Gambling offers
You can't consider an exchange to be scamming people for such reason. They are just offering.
Unless they are forcing you to use your funds to gamble there, then you can call that as a scam.
Scammers do not force, they lure. Normally, exchanges are for trading, not for gambling. There are gambling sites for gambling. The gambling on most exchanges are just to lure people to invest on shit coins. And they can lose. So, it is an indirect means of scam.

Aurora is Basically a cloud mining service that offers 10% per day cash back after you invest a minimum amount in form of bitcoin. It is crazy but it seems to run well at this time. Many people put a lot of money into that. It is clearly a Ponzi or fake

Be careful of ponzi, they are scam and run with investors funds. It can run fine now but later or sooner will tell.

Most cloud mining these days are now ponzi and scam.

Shitcoins on shady exchanges
Conclusion


I have some experience about cryptocurrencies now, I decided to share my experience with the members of this forum and the people that see this online. Although, it may not be new to many members of the forum but I believe few people will gain from this. I have realized if any exchange is legit or scam, there is always possibilities of scam, aside avoiding scam/fake exchanges, there are common few things to know about some legit exchanges also that can actually lead to scam for novice/newbies. Also, there are some transactions that supposed to be completed successfully but made uncompleted as planned by scammers. That said, fake exchanges also are not left out. 

These are what I have known so far (not all happened to me, I also avoided some)

1. Fake exchanges
There are some exchanges created for no two reasons but one, to scam. It can be a fake exchange from scratch or created to mimic the name and/or website of a trustable exchange, This can be worse to an extent of even downloading a fake exchange app on app store, that is why good research before choosing an exchange is very crucial, the best site for such research is Bitcointalk.org and I am happy to be there. Another source to these fake exchanges are phishing attack like through email, also are fake sites and social media. The fake exchanges can be known later to be scam but it would be too late for many novice.
 
2. High yield return investment scam
There are many scam exchanges that offer high yield return of investment to people, this is to decoy people to register and pay into the exchange account as fast as possible, but led to scam. These can also happen on legit exchanges, which means not all legit exchanges can be trustworthy as some can be shady in business, especially to newbies that just joined the exchange. I will like to make an example with the simple calculation below. 

For example (how it happen can on legit exchanges)
I will be using unknown coin W with $1 price before investment that later reduce in value to $0.1 after 1 months period.
Coin name:- W
Investment plan:- 10% daily profit
W price:- $1
Amount invested:- $1000 = 1000W

Daily gain = 1000W x 10  =  100W
                                100

Monthly gain = 100W x 30  =  3000W
Monthly gain:- 3000W = $3000

Monthly return = Monthly gain + Initial capital
                           = $1000 + $3000
                           = $4000
                                           
W coin technical analyisis during the 1 month period
Price at start of investment:- $1
Recent price = Price at the end of investment:- $0.1

Investment gain = investment capital x recent price
                             = $4000 x 0.1
                              =$400

Net profit =investment gain - Initial capital
                  =  $400 - $1000
                  =  -$600

Loss = $600

From the above calculation, it is clear that with the 10% daily return, investors that invested 100% capital lost 60% within the period. Experts could know this is just a trap, novice will not decide to analyze the coin but to just invest and thinking about taking profit after the end of the month, but talk loss. Also, the coin can be new on the exchange and not analyzable, making greed to tempt. This is just an illustration, some exchange can use another ways of investment plan but the losses can even be more.

3. Scam trading
This mainly happen on some shady legit exchanges, the loss is even less than a second, it happens immediately you make a trade, this kind of trade is always getting successful without any delay and the market is readily available to make such scam trade, making traders to lose. For illustration, I will be using bitcoin, tether and above A coin as an example.

Trading capital:- $1000
Bitcoin price:- $10000
A/USDT:- $0.00000001
A/BTC:- $0.000000000001

Using tether to make the $1000 worth of trade
1 tether = $1
A/USDT= 0.00000001 (legit)
A = 100000000
For $1000 = 1000USDT
A x 1000USDT = 100000000000
1000USDT = 100000000000A

Using bitcoin to make the same $1000 worth of trade
1 BTC = $10000
W/BTC = 0.000000000001 (legit)
For $1000 = 0.1BTC
A x 0.1BTC = 1000000000000
0.1BTC = 100000000000A


Scam exchange tactic
1BTC = $10000
A/BTC = 0.00000001 (scam)
A = 100000
For $1000
A = 100000000 = 1USTD =$1

Loss = $1 - $1000 = -$999
Loss = 999

The scam exchange tactics works in a way they represent bitcoin minimal amount to be 1 satoshi, even if the actual coin to trade against bitcoin is less than 1 satoshi, that is where the losses ensue as you can see in the above examples. No matter how high the amount of bitcoin you use to convert to coin A, your bitcoin will only worth $1 after the conversion, even if millions of dollar is used for it. That is why some experts do advice traders to use cryptocurrencies that are low in price like stable coins, doge or any other low price coin for the conversion. But the fact still remain, many new traders and investors are falling victim of this scam.


4. Gambling offers
100% people joined exchanges because of trading and investment, but some exchanges can offer gambling, there can be an option to gamble even before investment, the exchanges make the investment more attractive with high reward by luring users to gamble. Someone people gamble and lose their bitcoin or other funds, some also still could gamble little but the investment turned losses as explained above. Such gambling on exchanges is completely one type of scam.

6. Meet in Person
There are some ways bitcoin can be bought or sold locally, the counterparty can request to meet you personally before making any trade. This can be very dangerous as the counterparty can rob the buyer or seller. Also, another issue is exchaning fake fiat for bitcoin. Certain precautions must be followed in a way no one will scam another. Using p2p exchanges to escrow the funds will be a good option, and also all possible things you can think to make the exchange successful is good, like having a bodyguard around.

7. False/fake messages
Some scammers make use of fake messages to scam victim, but the way to avoid this is to never release bitcoin from escrow until you receive payment. Did you hear about a scammer that Spoofs sms identifier to steal funds from bitcoin user? The attacker/scammer uses a fake sms to deceiving the seller to release bitcoin from escrow, later, the seller realized the message was fake and no money sent. You can read the whole news on cointelegraph using below link.

A Bitcoin exchange transaction resulted in a user getting scammed as a spoofed SMS message from a payment app made it seem that the attacker executed the payment.
https://cointelegraph.com/news/scammer-spoofs-sms-identifier-to-steal-funds-from-bitcoin-user

8. Shitcoins on shady exchanges
This can be on many exchanges, it is even common on reputed exchanges, but it is trader and investor that will know a coin to buy or not, technical and fundamental analyses are important in this case. Shady exchanges can be more dangerous as they have many shitcoins that often become dead and never rise back possibly. And also, shaddy exchanges are not tired of listing many other shitcoins that will eventaully become dead.

Conclusion
Bitcoin and other cryptocurrencies  are not scam but people and exchanges can scam victims, we should not trust any exchange, asking people about such exchanges first is better, this forum, bitcointalk will be of great help in getting answers not to get scammed. We should be wise, knowledgeable and patient, we should not be greedy while dealing with exchanges. Not only exchanges though, but all aspects of life.

"But what if I convert my BTC to altcoins for faster transfers?" This could work if your funds are on exchanges in the first place(which is definitely not recommended), though also take into consideration the exchange fees, because you might end up paying more on conversion fees than just straight-off paying a decent bitcoin transaction fee.
Custodial exchanges charge higher fee that could be 10 times more than normal transaction fees. These higher amount are for exchange maintenance, but the trading fee could be low.

For noncustodial exchanges, the transaction fee is low while the exchange feels is high, you are right.

Waste of funds for fee or excanging.

Making my bitcoin transaction on my noncustodial wallet has been the best, the last transaction I made was sent with $0.1 dollar transaction fee.
8248  Bitcoin / Bitcoin Technical Support / Re: lost BTC on: August 14, 2020, 08:38:20 AM
I transferred 444 USDT from my Binance account to electrum wallet and just received 0.0054 mBTC !
The transactions is confirmed already, that is why you received 0.0054mBTC on electrum, but electrum support only bitcoin, that is why your tether transactions is invalid on electrum. But the transaction itself is valid.

how did it lost?
The coin is not lost, and you can get back your tether. All you have to do is to look for a wallet that support tether omini layer, using coinomi or any other wallet that support omini layer tether addresses are examples. Import the private key of your electrum address (that you send the tether to) on the new wallet (that support tether). You will see your coin on the tether balance after successful private key importation. But omini layer compatible wallets only support P2PKH addresses, bitcoin addresses that start with 1.

For segwit addresses, this link will be helpful
https://github.com/OmniLayer/omniwallet/wiki/Recovering-funds-from-a-Segwit-Address

Also, be careful next time, you are only lucky to have sent to a noncustodial wallet, that is why you will be able to get your tether, if supposed you have sent it to custodial wallet like coinbase, very possible your coin is lost forever as you have no private key given.

can I cancel the transaction?
Also know that transaction is not reversible, it can not be canceled after 1 confirmation. You transaction is confirmed already and also can not be canceled.
8249  Other / Politics & Society / A vaccine too early could be dangerous. on: August 13, 2020, 12:32:56 PM
Is Russian vaccine (sputnik-V) not too early for 3rd phase testing? Russian officials have said they plan to start mass vaccination in October which is considered too early for the phase 3.

Phases of vaccine testing and approval
https://www.cdc.gov/vaccines/basics/test-approve.html
Clinical development is a three-phase process. During Phase I, small groups of people receive the trial vaccine. In Phase II, the clinical study is expanded and vaccine is given to people who have characteristics (such as age and physical health) similar to those for whom the new vaccine is intended. In Phase III, the vaccine is given to thousands of people and tested for efficacy and safety. Many vaccines undergo Phase IV formal, ongoing studies after the vaccine is approved and licensed.

There are thousands of people that will be given the vaccine during the phase three. From BBC news, I read these comments:
BBC News - Coronavirus: Russia calls international concern over vaccine 'groundless'
https://www.bbc.co.uk/news/world-europe-53751017

On Wednesday, Germany's health minister expressed concern that it had not been properly tested.

"It can be dangerous to start vaccinating millions... of people too early because it could pretty much kill the acceptance of vaccination if it goes wrong," Jens Spahn told local media.
"Based on everything we know... this has not been sufficiently tested," he added. "It's not about being first somehow - it's about having a safe vaccine."

Elsewhere in Europe, Isabelle Imbert, a researcher at the French National Centre for Scientific Research in Marseille, said promising a cure too early could be "very dangerous".
We do not know the methodology or the results of their clinical trials," she told Le Parisien.

And in the US, the country's top virus expert, Dr Anthony Fauci, said he doubted Russia's claims.
"I hope that the Russians have actually definitively proven that the vaccine is safe and effective," he told National Geographic. "I seriously doubt that they've done that."

Meanwhile the Moscow-based Association of Clinical Trials Organizations (Acto), which represents the world's top drug companies in Russia, urged the health ministry to postpone approval until after phase-three trials.
Acto executive director Svetlana Zavidova told the Russian MedPortal site that a decision on mass vaccination had been carried out after combined first- and second-phase tests on 76 people, and that it was impossible to confirm the efficacy of a drug on this basis.

What do you think about this?

Despite rapid progress, most experts think any vaccine would not become widely available until mid-2021.
8250  Bitcoin / Bitcoin Discussion / Re: Should we promote acceptance of "zero-conf transactions"? on: August 13, 2020, 10:16:53 AM
One of the solution to reducing transaction fee is the lightning network, but many people are not using it for now because it is still under development, if fully developed, it can be used for cheap payments like paying for coffee etc. These should even be the main purpose of lightning network (to make payment of small amount of bitcoin)

Another is the use of segwit (bech32) addresses, with the use of such address and sending to such address, transactions fee is reduced in relation to the transaction weight. But this may not be satisfying enough.

There could also be other development in the future that can be used to reduce the transaction fee.
8251  Economy / Economics / Will African countries be developed? on: August 13, 2020, 09:28:18 AM
Africa, a continent to billion of people, having many agricultural and mineral resources, it is home to many tourist centers. Africa is located in region not subjected to many natural diseasters like earth quake and hurricane. Africa so blessed to be a continent that can run on its own with the natural resources they have.


https://www.aljazeera.com/indepth/interactive/2016/10/mapping-africa-natural-resources-161020075811145.html

Despite all natural resources embedded in Africa, they are always lacking and behind other continents. Most if not all the countries in Africa are regarded as third world country (poor nations). Why are Africa countries remaining underdeveloped or developing when they have what they can use to grow and develop.

In Africa, getting good education is not easy, rich people and the so called politicians are getting quality education for their children abroad, if they are ill, they travel oversea for treatment, good example are the governors and presidents in Africa including their relative, they make the Africa hospitals not suitable and good enough for medical teatments, that is why many Africa medical practitioners are travelling oversea and never coming back too. Corruption, nepotism and thinking of their families but not multitudes has devastated Africa into a poor standard of living nations. After all these, Africa countries lack employment while most that are employed are underemployed, making them to be poor countries truly. There have always been persistent increases in inflation, this makes me conclude African leaders are not capable to making their countries to be developed.

What makes me more sad about all these is that Africa countries can not make use of what they have properly (natural resources), and now the world has moved more towards technology, how will Africa properly handle what they are lacking. Technology wise, Africans are nothing in the world for now.

I am just thinking if all these can change, I wish many Africa countries to be developed. What can possibly lead to Africa countries getting advanced so the quality of living in the continent will improve?

8252  Other / Serious discussion / Re: 12 Coronavirus Autopsy Cases Reveal TRUTH About How Coronavirus Patients Dying on: August 13, 2020, 07:54:58 AM
try looking at NHS websites
in 30 seconds i found 2 studies..
one done using deaths between feb-april
and another from feb-august

where it was 3-4% of people died with no co-morbidities (many hundreds of people(atleast 1300))

so as others suggest. i think its your inability to use google. or avoiding actually getting results that make you not find it

so just actually try finding the data instead of lame excuses to avoid it
If 3-4% people with no co-morbidities died, this means the number of people that died this way are not much if compared to people that have other disease before contacting corona virus.

3+4 = 7
7 ÷ 2 = 3.5
100 - 3.5 = 96.5

Cross multiply
3.5   = 13000
96.5 = x

3.5x = 1,254,500

X =  368970 people = people that died with co-morbidities, if assumed 13000 people died with no co-morbidities.

Which means people that wouldn't have died if healthy would have reduced.

Mixed economy has been the best, and it is being practiced in European and North American countries. For the goverment to carry all the whole burden can not do the economy good in this time of 21st century.

Normally, the world can not be balanced, there are shits, a world that favour the rich, and are getting richer but not favouring the poor, and the poor becoming poorer. More insight into this, individuals may not be blamed but the governments which are affecting the well circulation of wealths.

Also, many people in the world now, instead helping people, they are more for fame, that is why someone can buy a cap as expensive as that.

That means you are using the phone version, you need to use the computer version. You will be able to edit the fee.

You can important import your phone version seed phrase on a newly downloaded desktop version, your wallet balance will be seen. And you will be able to use the fee control (fee editing)

If you are still confused, this is how to reconsidate the small inputs on your electrum wallet.

Quote from: LoyceV link=topic=2848987.msg29228128#msg29228128 date=1517308445
[size=3
How
Now the tricky part: it depends on your wallet! The easy way would be to just send your entire balance to a new address in your own wallet. Make sure to manually set the fee!
I prefer to "Enable coin control" in Bitcoin Core, you can do this in Electrum too. Select the inputs you want to use, and leave out very small dust inputs (say 0.00001BTC, it would still cost more in fees than it's worth). Then simply send all selected inputs to a new address of your own.
If you have many different inputs, I suggest to consolidate them in multiple steps. Don't create a 100,000 bytes transaction with 500 inputs, but instead create many transactions with 20-ish inputs.[/size]


So, you can use your electrum wallet to generate a new address, send your total balance on the same electrum wallet to the address generated. Use the fee control (edit the fee for the transaction), and send the total balance btc amount to your own wallet using a very small transaction fee. With time, the transaction will be confirmed. If later confirmed, you will be able to send btc with low transaction fee again on the same electeum wallet. If such issue asked by you is happening again, you can consolidate again.

The phone electrum wallet can not edit the fee, so, the computer version is good for consolidating.

Just a good advice, leave a space after each commas, to make your post easily readable.

You are right, but we should be careful of scammers, also study well about bitcoin trading and investment. But, because you are looking for ways to earn, do not put pressure on yourselves because you can also lose if you invest with low quality mindset and with lack of patience. You need to study how the market works and well analyze bitcoin before starting at all.

Bitcoin has helped truly during this pandemic, especially for payments across the borders, and also for other online payments, no need to touch it like fiats, which means it can not aid but only prevent the spread of corona virus.

the funny parts are UK is only phase 2 stage also. but already preping for mass population usage
and also 100m doses just for the UK...... theres only 65mill people and not everyone will needs/want it..
This is not fun at all, you have actually pointed out the truth. I have gone through the link you provided and from it I saw another link:

Oxford vaccine triggers immune response
https://www.bbc.com/news/uk-53469839

Because of the short period of time, they have not run for long enough to understand how long the antibodies (against the virus) produced by the body will last, the study in the Lancet showed. But, as time goes on, this will be known. Over 90% UK patient that were given one dose of the vaccine showed positive result while the remianing 10% people showed positive result after given 2 doeses of the vaccine. You are right. And this is just still second phase of testing.
