Bitcoin Wallet - Secure environment + users have full control over fees.
BRD - the most user-friendly.
BLW - with Lightning Network support.

Bitcoin taxation is essential and inevitable part of its adoption.

Are hardware wallets still the safest ones? Hackers got an access to users' info like emails and etc, but the funds weren't stolen. Now I don't know if I should buy Ledger wallet.

Now there are more rumors about their plans to ban crypto. They can't ban Bitcoin, it's true, but trading and mining are likely to be illegal in Russia.

Coinomi is one of the most popular wallets, maybe due to its features and strong reputation. I like using the app because of built-in exchange, no KYC, no IP association, no identity linking and supporting Segwit. Coinomi is a good choice.
p.s. Coinomi is closed-source, but who is really going to review their code?

It depends on how you would define a good store of value. If it must be stable, Bitcoin isn't the store of value. But despite its high volatility, Bitcoin is deflationary, so it can be a reliable long-term store of value.

Well, it's evident that most of people have no idea about Bitcoin. So what's your suggestion for making it more popular? I couldn't understand it from your post.

Crypto-only economy is nothing more than the libertarian day dream. When some countries ban cryptocurrencies right now, it isn't possible.

Theoretically blockchain was the first. The first work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta. In 1992 they incorporated Merkle trees to the design, which improved its efficiency by allowing several document certificates to be collected into one block. But the fist "modern type" blockchain was conceptualized by Satoshi Nakamoto. Although, now blockchain is separated from Bitcoin, Bitcoin can't exist without blockchain.

One thing to note - Bitcoin dips are relatively and unpredictable. I thought that $6k was a bottom in March and accidentally Bitcoin fell to $3,8.

Maybe the USA will follow Latin America's path. Now region holds the largest number of cryptocurrency users in the world merely due to hyperinflation.

Miners will still be incentivized to validate the bitcoin blockchain because they will collect transaction fees from users.

When the global market is down nothing can be a reliable store of value. Now everything is decimated. Bitcoin isn't an exception + get into consideration its volatility.   

Launching new projects, which will be similar to already existing on the market ones, is absolutely useless. We have enough coins already, now it's better to concentrate our attention on developing and upgrading reliable crypto projects and make cryptos with good reputation more attractive for users.

Legislation crypto in any possible country is very important for the community in general. It's a one more step toward the better future and maybe the cashless society.

It will be so expensive solution to be useful.

Bounty hunting has become a core component of the cryptocurrency community and is being leveraged by exchanges, established companies and start-ups. But nowadays earning on bounties is completely hard. No everyone understands it, unfortunately.

One satoshi for $1 is impossible. Now Bitcoin is at $10,000 mark, it will be bullish, but not so long, or it will take centuries.

China has one of the most strongest economy in the world. And I'm sure that they are against printing money on the side.

Bitcoin can challenge the banks. But at this moment we face one problem: the banking system is controlled by the government. And the government won't let it happen.   Another thing is that Bitcoin is more volatile, and some people can't stand it.
