That is crazy, why would they make such claims now? We all know already that COVID-19 is spreading through. Saying otherwise is just foolish and should not be allowed by official government agencies. Just look at the mass spreading of corona in the beginning. They happened at mass gatherings where 1 person would affect 200-300 other people without any physical contact. Of course the virus is spread through air.
Try to read the news in the link posted by the OP. They are only referring to far distance of 6 feet or more, that the virus may not spread through far distance. They still hold to the fact that covid-19 can be spread through short distance in humans droplets through the nostrils. |

Everything about bitcoin is decentralized, there is nothing centralized about it at all. Any improvement that want to be made will be first be addressed by the bitcoin community, it is either agreed upon or not accepted by majority. This are the cause of the bitcoin hardforks like bitcoin cash.
Bitcoin supply is 21 million, bitcoin community know how that value is very important, any increase or decrease to it will disrupt bitcoin as a whole. But let us use the scalability issue as an example, this was seen as a problem and was brought up to the community, it was addressed but majority did not go for more blocks to be created which will lead to increase in transaction time, but due to one reason or the other, majority did not voted for that and lead to the hardfork known as bitcoin cash.
That is just one example. One thing I like about bitcoin is that it is completely open source and nothing can happen in a centralized way as it is completely decentralized.

Well it is a respiratory virus, so it spreads through the exhalation of infected people. That sounds like air to me
The formal claimThe health agency had said COVID-19 could spread through airborne particles that can remain suspended in the air and travel beyond six feet The new claimCurrently, the agency’s guidance says the virus mainly spreads from person to person through respiratory droplets, which can land in the mouth or nose of people nearby. What Trump saidEarlier this month, US President Donald Trump took exception to comments from the CDC director, who said masks might be even more effective than a vaccine for the novel coronavirus that could be broadly rolled out in mid-2021. Check this also The UN health agency still believes the disease is primarily spread through droplets, but in enclosed crowded spaces with inadequate ventilation, aerosol transmission can occur, said Mike Ryan, executive director of the WHO’s emergencies programme. https://www.aljazeera.com/news/2020/9/21/us-cdc-abruptly-pulls-covid-19-guidelines-on-airborne-spread
People are just seeing this in a wrong way. The virus is still claimed to spread through droplets from infected people which is still through the air as you suggested. But, for a spread over a long distance might not be the possible. |

Electrum is an outlier which uses its own seed phrase algorithms. You can import BIP39 seed phrases from elsewhere to Electrum, but you can't import Electrum seed phrases in to most other wallets.
I have just downloaded a coinomi wallet on another device, I imported the seed phrase from my electrum wallet into the coinomi but it did not work. You are very right. Later, I read seed phrase generated on mycelium, copay, bitpay, jaxx, ledger nano, keepkey, trezor, blockchain, exodus and trust wallets can be easily imported on coinomi. Also, I do the same for electrum by importing seed phrase from coinomi into an electrum wallet, not also successful as it did not bring out the next button. I used electrum seed on the new electrum wallet and it brought out the next button. I later know all the wallets mentioned above support BIP44 but electrum wallet did not support BIP44, which is the reason the seed phrase generated on electrum wallet will not support most other wallets. The wallets above are not all recommendable, only for informational purpose. Like me, I prefer hardware wallets, mycelium and trust wallets. Including the electrum wallet in question. |

I do not even get the reason people will be using a wallet that support email. Email is another means a wallet can be hacked, a wallet that provided someone with seed phrase, why email again. To compromize someone's email is easy for hackers as many people are not using 2fa to protect their email. Unlike the best noncustodial wallets that does not require email at all.
Only seed phrase is enough for backup, no need of any email at all. The seed phrase should be properly written on a metallic sheet, or paper and laminated. Which means the back up is offline. If protected, nothing will happen.
We should also be careful of hackers, they can make use of malware like keyloggers, trojan horse and many others to perform malicious activities on our wallet device that can lead to loss of funds. But specifically, using blockchain wallet is more risky as it requires emails which can be used to compromise the wallet if attackers knows about it.
Better use safe wallet like electrum for bitcoin or coinomi for multicurrency purposes.

For example if you multiply the USD rate of 1 BTC with the CNY rate, its 1 BTC = CNY 73,600, but exchanges there have it around CNY 75,500.
In other countries in Asia and South America also BTC is more expensive to buy in non-USD currencies than in USD.
Why is this the case?
You are getting this wrongly. The price of bitcoin differs from one exchange to another, and also fluctuating. The difference is what is confusing you which is as a result of trading volume on individual exchanges. |

On online wallet, that does not mean you can not have your private key. There are two types of online wallets, noncustodial wallets have private keys. Electrum above is totally a noncustodial wallet that have its own private key. Although, the person can make use of electrum for such if he has the experience to avoid malware and hackers. But, it is still not wise enough, holding such amount on online wallet truly still make the fund less safe. Getting harder wallet will be the best option. On hardware wallet, the private key is completely stored offline, they are resistant to malware, they are the safest to use with more of convenience. But, it should still be known that no wallet is 100% safe, some malware can still penetrate hardware wallet that can steal bitcoin from the wallet. So, we still need to emphasize on the fact that despite hardware wallets are the safest to use, there should still be 100% avoidance of malware for safety. |

I do not really understand this. But, I did noticed before I started being careful of the internet, I did click on links that can redirect me to two or three sites at a time. Which means, it is possible to install a malware from such redirect websites which could be from malacious actors. I get that point.
But, I do not notice such site again, maybe because I am too conscious of the internet nowadays. It is very good to be mindful of the sites we do visit. There are many sites that operate like this, installing malware into peoples devices. I am now even getting to the point I do not use the device that I have my wallet, crypto exchange and banking apps for other online reasons than to be used for only the specified purposes.

As of the time I was writing this, there are 10115 crypto ATMs in the world. I checked this directly on coinatmradar ( https://coinatmradar.com/). I remember in 2019, there were only about 6000 bitcoin ATMs in the world, but the increase in this year to an extent there are over 10000 ATMs now is a very good move which is also helping bitcoin and other crypto adoption. With time, crypto ATMs will increase over 100000. The increase in crypto ATMs is an evidence of increase in bitcoin and other crypto adoption. |

9.If you lose your private key (Bitcoin wallet), you lose your Bitcoins.
You store your Bitcoins in a digital wallet. You can log in and check your balance. One thing, though, you have to be very careful when it comes to storing your password and key, which is what allows you to access your digital Bitcoin wallet. If you lose this access, you’ll lose access to your Bitcoin wallet and the amount you have inside.
You need to know how private key and password are different. Password only give you access to the wallet on your device. If the password is lost, you can still use private key to recover back your wallet on another device. Also know that seed phrase can be used also to recover back the wallet, so far the wallet support BIP39 seed phrase. 17. Bitcoin creates a lot of energy
Bitcoin mining is a big business and it requires vast amounts of computer processing power. Various estimates of just how much CO2 it uses equate to around one million transatlantic flights, or the equivalent of the energy output of the Republic of Ireland, New Zealand, Hungary or Peru.
Basically, if Bitcoin miners were a country, they would rank 61st in the world in terms of electricity consumption. It has been said that around 2.5 million people could be powered by Bitcoin mining and this is something we have to consider in the future.
While Bitcoin has undoubtedly disrupted the technology sector in recent years, its incredibly wasteful process needs to be improved.
You are not fully right, bitcoin consumes electricity but it is not a waste of energy, bitcoin even produce energy. So far the electricity used are legal and are paid for. It is even helping the electricity company to have a service to provide. About it adding to global warming, what about all other human activities that added to global warming. The significant reason that scientists have proven to cause global warming is deforestation not bitcoin mining. You do not talk about Amazon wide fire, or the wide fire in California and in many places of the world that are reducing the trees that makes carbondioxide to trap more heat into the earth. Also, governments and private sectors providing the electricity can move away from sources that produces greenhouse gas and move towards the ones that do not produce greenhouse gas. 14. Bitcoin transactions cost almost nothing
This has unfortunately changed and it's now a bit more expensive to use Bitcoin than some people could afford. This actually helps create Bitcoin a safe haven asset though, as it is quite costly to pay miner fees for everyday transactions - especially if you want them to be quickly confirmed.
I get your point, you are definitely right. But, I still like bitcoin for one thing, I can still make transactions with as low as 15 satoshi per vbyte or even lower. I still make use of low fee a lot. But, what is now important is to use of low fee but a fast clearance time. Normally, the lower the fee the higher the time before confirmation. Bitcoin transaction scalability need to be truly addressed. But, I noticed OP compared it with PayPal and other normal fiat transaction which have higher fee with constant price, but bitcoin fee is not constant and still lower to such. Only the clearance time is the issue as of now not the fee in we look deep into it. |

What's your take on this new development in my country?
First of all, about the issue of scam, regulation of cryptocurrencies in Nigeria can help to certain extent but people will still be scammed. People are gotten scammed because of greediness and mostly because they have no knowledge about what scam is all about. Regulation of cryptocurrencies in Nigeria does not mean some people will not still visit scam sites and pay bitcoin into scammers bitcoin account, it does not mean someone will not use his or her crypto wallet device to browse online the way he likes and be infected with malware that can totally compromise the wallet. About scam, we need to fully have real understanding about scam in order to avoid it. That is why being in a forum like bitcointalk will really be helpful. Scammers are beyond government regulations, but like the OP implied, scam activities will certainly still reduce. I'm also having a mixed feeling about this getting abused (manipulated) to their (the government) selfish interested in the sense that they mandate any company wanting to operate in Nigeria to cooperate with them in leaking users sensitive information
We should expect that. Especially, if someone is suspected to have a criminal activities, such information can really help them. But, normally, this does not really apply to people that are professional and know a lot about cryptocurrencies. Like me, I hate kyc or any other verification, and I can not do it. Someone can easily trade on many exchanges without any kyc and also operate his wallet without any kyc. But, most people will not know all these but only even thinking kyc is good. Although, Imo, this is a good move by the Nigeria SEC, even this can lead to increase in the rate of crypto adoption in Nigeria. But that does not still affect or compromise the privacy of crypto experts in the country. |

There are actually multiple vectors of attack for different hardware wallets. Ledger for example had a bug where when transacting altcoins, an attacker could trick your device in to also signing a bitcoin transaction. Trezor have a vulnerability where someone with physical access to the device can extract the seed phrase.
You are right, there are many information that is misleading online. I have later known that there are malware that can even penetrate the random number generator itself to reveal a private key. There are truly vulnerabilities in some even so called hardware wallets that can reveal the seed phrase also. The best we can do, it to make sure we connect a device (phone or computer) that has no malware to hardware wallet for it to be safe for use. Malware are deadly generally. |

My question is - I have a few btc addresses with their private keys. Is there any Hardware wallet wherein I can just store these private keys of mine and authorize transactions instead of using new wallets generated by Ledger or Trezor?  ?? I hope you have been answered. But for more explanation in a way you will understand more. Normally, you are having a private key, or seed phrase to that private key, you can import the seed phrase to hardware wallet so far it is BIP39, or directly import the private key like you wanted. But, remember the seed phrase is generated not through offline means which makes it not as secure like the one you will generate on hardware wallet itself which will be offline. So, not that you can not do it, you can import the private key to hardware wallet but it does not make any good sense in term of security, that is why you are advised not to do so. Just generate your private key on the hardware wallet, the private key will be offline, which means nothing can penetrate it, it can not be revealed to hackers. Then, you can send your bitcoin from the old wallet into your new (hardware) wallet. If you are not in haste, you can send the bitcoin using as low as 1 satoshi per vbyte. But I will recommend 15 satoshi per vbyte. Also, know that hardware wallet is resistant to malware but there is still certain type of hack that can happen to any hardware wallet. We still need to be careful of malware.

Nice article OP. One of the ways people can really make money is through affiliate programs. I have found out that even all the legit businesses like faucets that are not profitable is still profitable in term of being a referral. I have seen many exchanges that pay people some certain amount of the trade the person they refer use to trade on the exchange for certain period of time. But, normally, affiliate program could be easy for some people but difficult for most people to use it to earn. For example, someone like me, I have no website that people do visit, I have no channel, I have no online means to make people to be referred through my link, all I could refer are friends and families, this can not make me have enough gain. There should be means people will do visit the page the someone's referral links are, such as having a website that people do visit, having a channel on telegram, through social media and many others like apps monetized with ads. Affiliate program is a very good and profitable business, probided if many people are referred through someone's referral link.
Also, we should be mindful of the site we are referring people to, knowing the reputation of the site, checking the domain, making sure it is not a scam business. But I noticed many sites do not check all these but even referring people to scamming sites. Which means we that is being referred need to also be very careful of the site we are referred to, for us not to be scammed.

Bitmain is the owner of antpool, antpool has been the largest bitcoin mining pool at one time before, but they have never had more than 50% mining hashrate capacity before. You can check the the link below posted by tranthidung
Your data interpretation is not correct. My analysis is for total number and corresponding percent of blocks found by different pools in specific years or all time. Total block found in a whole year, 2017 ie. does not reflect how low or high one company, pool controls total hashrates on the Bitcoin network. It is a very different data. In the other words, pool with dominant hashrates find most of blocks in the period its hashrate is dominant on the network. Sure it is not a year timeframe. Definitely not if you are mentioning about dominant hashrate about 50%.  But if you simply and naively rely on total blocks and percent of blocks found by one pool to get very raw overview on potential hashrate of that pool, you have to look into very narrow timeframe, such as 1-day, 1-week, or 1-month. I remembered such FUDs back in 2017 or 2018, so when I have time I will come back with data for those 2 years and see what I can find from dataset. Thank you for the correction. I have deleted it for not to mislead people. |

Why would they think it was subject to a 51% attack before. I'm not sure if the testnet has been subject to one actually (or an isolated version of the blockchain from the start to check its reaction to it).
What the article is trying to convey is that 51% attack is possible on bitcoin blockchain, but the way it was conveyed is so misleading and inaccurate. Bitcoin blockchain with the hashes generated and the way it is generated that is not in a centralized way will makes it not possible as we all know. Which means bitcoin is not subjected to any attack. I don't know to what extent the article pasted in the OP might be, maybe the author used his/her words in the wrong contest that defeats the message he/she wanted to pass across but then, here are my thoughts on the OP.
Exactly. That is what actually happened. The wrong usage can mislead novices. |
