Yes Bitcoin will be fine. If she wins there might be a temporarily dump like we saw when he was losing the debate but in the long run it will be fine.
Yes, a temporary dump is possible - but only if Bitcoiners still insist that Bitcoin depends on US politics ;P
But if Gensler is still in the SEC and he keeps suing all these tokens which he calls unregistered securities then we will get issues with many non-bitcoin type of coins.
Maybe. But would that affect Bitcoin? I believe the altcoin market is much more dependant on Bitcoin's moves than Bitcoin is on the altcoin market.
The exceptions may be memecoins, which are more like a casino and are according to a
recent study are the category of coins with most chances to move in a "contrarian" sense than Bitcoin and thus could be used for hedging. This means however not that memecoins influence the Bitcoin price either. Only perhaps the Ordinals/Runes based coins could create some demand for Bitcoin but they are already dying and thus their influence may be minimal.
Thus, stricter regulations for altcoins would most likely not affect Bitcoin at all, or only minimally.
Weaker investor protections for ICOs, altcoins, service providers and DeFi, as written above, could even mean a higher crash risk. We've seen with Terra/Luna that a failed altcoin can influence Bitcoin negatively.
So bitcoin will survive but it would of been more successful if she didn't win the election.
I think the only Trump announcement that could really significantly affect Bitcoin's price is the creation of a Bitcoin reserve, i.e. the "Don't sell a Bitcoin" policy. It would not boost Bitcoin to the moon for itself, but could cause a 20-30% pump perhaps.
However, one would have to wait if this pump can be sustainable. If more countries follow that line and incorporate seized BTC into their reserves or even actively buy some, then this would indeed create a bigger pump. But it's also possible that US and El Salvador could be the only countries following this policy, and then the impact would be again not so overwhelming.
For mass/retail adoption, in contrast, I believe Trump's other announcements about Bitcoin at least are neutral.
