when he was president the first time. the IRS started making all those rules about how you had to pay taxes even if you didn't convert it to fiat. so his history is that he hasn't done anything to help people using crypto, bitcoin in particular. he's just sat by and let the IRS make all these rules. rules that hurt people using bitcoin.
i think he had his chance once and he dropped the ball. i don't know why he deserves a second chance.
But you can understand that politics is politics right? Trump can look for ways to make sure that he win Biden and become the next president of United States again. He will look for all ways to make sure that he can be there. Be saw that cryptocurrencies has become mainstream which means people are into it. He then used it against Biden as he wants people that are dealing in cryptocurrencies to vote for him. I think his strategy is helping him as this has given him more chance to become the president if United States. But as for the price rise, I do not see correlation if it to his assassination attempt.
