You need to know one thing that the government is behind running the banks and if people are slowly turning to bitcoin and giving up banking. What would make you think the government will legalize bitcoin more in the future when it harms them more? I'm a bitcoin investor and love it, but the reality is the banks in the US are in turmoil, but the world banking industry is fine right now, and people continue to believe in it.
One more thing bitcoin is a better alternative than spreading it will be a replacement for the bank, war with the banks or government has never been in our favor.
As for El Salvador, I'm not saying they failed, but we haven't seen them grow since accepting bitcoin as legal tender, and they're just a small country, nobody will care, and they don't affect the world economy.
Yes, that's my point. It's obvious that government will do anything to spot bitcoin from becoming a currency. That's why they can even use this trend to say "yes guys, bitcoin is an asset and you can trade it, but we will tax it. But you won't use it as a currency". And it looks like the majority of people will be happy with that because everyone just ignores bitcoin being a currency.
That's why it's literally our fight against governments at this point and out community should protect bitcoin at all costs. But right now I don't really see that people care that bitcoin is in danger.
