Trump promised only 3 things. Free Ross Ulbricht on day 1 of his presidency, protect the right of self custody and reject the creation of CBDC. However, these things do not signal a real friendly administration to the cryptospace. I am also very skeptical if he will free Ross Ulbricht on day 1 heheheheheh. The list in my reply is what I reckon would certainly signal a real friendly administration towards the cryptospace. If they do not do this, I would be quite certain that they are not procrypto.
Trump's rejection of CBDCs aligns well with the crypto community's interests. No one wants to use something that can be easily tracked and traced by the government. This should be more than enough to help Trump win the support of crypto voters. Freeing Ross Ulbricht and establishing a friendly regulatory environment for Bitcoin is a huge plus. We all know how things went down for the crypto industry after Biden took office. Several crypto exchanges left the US (eg: Bittrex), while some services stopped dealing with US customers.
The only good thing the current administration has ever done for crypto is the approval of spot ETFs. But that's because the SEC had no other choice (especially with Grayscale's victory in court and rising interest/demand from giants like BlackRock and Fidelity). Crypto voters will choose a presidential candidate who aligns with their interests. And Biden is not the one. We'll see what happens after Election Day.
