Let me be specific to only bitcoin, Biden or no Biden, Trump or no Trump, bitcoin will always prosper. Its prosperity is not in the hand of anyone because it is not a centralized currency, it is completely decentralized and open source. People are getting to know it and embrasing it. Let us just expert more prosperity for bitcoin as it is becoming the first truly sovereign currency.
It is really hard to predict what will happen next in crypto world in US when Biden won this election.
I'm only hoping for a positive happenings in bitcoin community and I'm not judging Biden's administration but I hope that he also cares about the cryptocurrencies.
But as bitcoin is really popular nowadays, and it become more popular during lockdown and quarantine, I think bitcoin will still prevail and have an increase in its price no matter what. As we know that bitcoin is volatile, we just need to observe the market and make a lot of predictions that we can rely on.
