It seems like he's using Bitcoin to get more votes. But this is also giving Bitcoin more visibility, which is a big plus.
If its about visibility, it's Bitcoin that is given trump the visibility here and not the other way round. Do you know that almost everyone around the globe now know and understand the use of Bitcoin most especially people that can access the internet, since people that hold Bitcoin want good adoption of Bitcoin, it will helps send a message that there is a person that cares about Bitcoin that want it grow but this are election promises that would end only as campaign promises, nothing will be actualize.
Don't forget that Biden is also trying to regulate the entire crypto market and since many investors doesn't like it as it will kill the objective of crypto, it will be an advantage if Trump promise to do the opposite and support Bitcoin and return, the entire crypto will think that Trump is the only candidate that cares about Bitcoin and hence he will have their votes. This is what they called smart moves in politics.
Im not totally on board with this. No doubt Bitcoin has high name recognition online, but that doesnt mean people really grasp it or actual use it regularly. Sure, a lot of people who use the internet have heard of Bitcoin, but how many can explain how it works or use it to buy stuff with it?
And while some politicians may talk about crypto when campaigning to seem hip, but lawmaking creeps along sluggishly. Though the bright side is, the more crypto gets discussed and understood by ordinary folks the more it will become part of our day-to-day.
