I don't think he's the mistake.
I remember he made Ross free and he support in Bitcoin as reserves.
Let's say whoever become the president and he implemented this tariffs, Bitcoin price might be far lower because there was no surge during the announcement of new president until the president officially take his chair.
I might be wrong about assessment but the support Trump gave to bitcoin was more for his political interest than the general good, Bitcoin was actually strategically seen as the easiest way to actually to gain the support of not not just bitcoin enthusiasts but also for all people who supports decentralization, this was more of his reason why he opted for bitcoin reserve support and why it is been still pushed just to honor his campaign promises. If trump was actually in for true decentralization there was no reason for launching/supporting a pump and dump coin.
If Trump wasn’t given this much relevance on this space I think the talks of even tariffs wars and the economic crisis wouldn’t greatly affect bitcoin as it is now. Bitcoin was here when the likes of Biden were against it, it survived bans from countries then, it would have been better off like that even now
