I don't think regulation of the US government have a major significance to the price of bitcoin at least with the current price surge, we can attest to that already. What pushes the market is sentiment. This is what different people feel and expect so they either rush in or go out of the market and that lead to a movement of price.
Its hard to determine nowadays what causes the price to increases especially now that there are still many economic and government problems affecting peoples decision whether to buy or just sell. The recessions, pandemic, war as well economic loss of other countries makes other investors to not pit more investment in crypto. Though seeing how the price increase in these early month of 2023 gives us hope that we are still capable of earning or getting more profit in bitcoin provided no negative issues will come along.
