I dont think that Biden is a supporter of cryptocurrencies, most likely he is either neutral or generally negative about cryptocurrencies like Trump and it does not matter who will become the next president of these two, because I do not think that in their main lists we can find something about cryptocurrencies, well, or in their lists it is only possible to find sketches about how to make more money from cryptocurrencies by taxes and other things, so no matter who will win, I think USA will have the same opinion about cryptocurrencies as in recent years.
