Never heard that president-elect Biden or someone from his camp made any public statement about bitcoin or crypto-technology, hopefully no tough regulations will be made.
Well,Biden and the democrats are leftists,so the taxes(including the taxes over our cryptocurrency profits) might go up.This is the only negative impact over the crypto industry I can think off.
Other than that,I don't believe that the Biden administration is going to be overall negative or positive towards Bitcoin and the altcoins.Maybe the regulations ,like KYC,will become more strict and the crypto enthusiasts will have to abide by new rules ,like proof of income source and proof of address,but I don't think that Biden will ban the crypto industry.
