Most probably warming up due to new updates in bitcoin community. No one can say it's a bull yet until it goes over 55k.
It's already the uptrend and we can already call it a bull trend if you are going to compare the price a year ago.
The market is getting better, and with the up coming Bitcoin update, this can also be a good preparation for halving though many are anticipating Bitcoin to have a price correction after halving, which I think is normal since many will sell the news. If you are uncertain about the market trend, better to play long and wait for the peak because its about to happen, we are just waiting for the right timing this year.
