The month of march has been a bearish period for Bitcoin since it's history and a lot of whales predicted it's price to go below 60k and probably rise again after March in the anticipated halving towards April.
Are you sure that you're not making a mistake here from what you're saying, maybe you're intended for bullish instead of bearish because bitcoin has been bullish since last month till now, maybe we may experience a little of its bearish any time soon or later in March, but as for now, we are still bullish in bitcoin market price, try and recheck your statement if something is not missing from what you've already intended top portray.
You kind of miss his line of point, OP means bearish month for Bitcoin in it. History and not that this month is a bearish month so far for Bitcoin, but I guess in the past pre-halving years,
And to answer your question OP, definitely I guess this is part of the reason and mainly the reason because on before the new Tether was printed, Bitcoin already started gearing up for this move, but now it will act as a catalyst to help get the price of Bitcoin where it's headed to, and besides where do expect those minted Tether USDT to go, Buying Bitcoin and other cryptocurrencies as well.
