There is a famous quote and it says:
"If there's a will there's a way"

Give up?? Very weak of a man if you will just give up on Bitcoin just because the government in your country are simply prohibiting you from using it. There are many VPN's out there that can make you secured and with that, you can still use Bitcoin or any other crypto. If you really want to use it then you will make some ways in order for you to use it .

On the other hand though, I will agree that there are some crypto investor who will choose to just give up because they are being banned to use it by the government. We can't blame them though but if there are some who are giving up on it, there are some investors who will enter and invest. Its just quite unfortunate for the people who are living in countries where they banned Bitcoin. They can move to other countries like El Salvador though if they really want to use it .
