He didn't regulate crypto with a "heavy hand" during his first term as President.
The current administration has done more harm than good to the entire crypto/Blockchain industry.
You should compare each administration with its predecessor not the next one.
It's a trend that is happening all around the world and not just in USA. Biden is worse than Trump, Trump was worse than Obama (Bitcoin didn't exist during Bush admin.). The regulations for the crypto world is getting tighter and tighter. Next administration will get tighter regulations as well.
I dare say that even if Satoshi Nakamoto were to become US president this year, the regulations, KYC enforcements, the banning of anything remotely privacy related such as mixers, etc. will continue at a faster pace.
Governments want control and despise losing it. They will not stand idly by watching people reach financial sovereignty and they will not accept not-being able to for example shut down all their bank accounts and seize all their money any time they wanted to. So they'll start hitting back...
We shouldn't think that a president can automatically change the operations of a country automatically. Some strong anti-bitcoin forces in the US Congress will do everything possible to sponsor bills aimed at regulating the Bitcoin ecosystem. Some regulatory agencies are independent and the President has no power over them, so it will be difficult to push them to make Bitcoin-friendly laws.
Although Trump is asking for donations from the crypto community, there is no way he can get more donations from the sector than what he would get from centralized financial institutions. Big banks and other institutional investors will give him the biggest donations and he would have to make policies that will promote their business. These laws will be anti-decentralization which will also give them the chance to control the system.
