The growth is happening in the fast phase. Myself saw the price of bitcoin around $40k and suddenly a notification popped Bitcoin crossed $44k along with ethereum $3100. It was completely unexpected, because the growth from the range of $30k to $40k took place all of the sudden and expected gradual growth. Now its time for short term trading profit as we'll see some fluctuation before crossing $50k.
Now, wondering where are those spectators who are waiting for btc to go down by 20k. I guess, they are regretting that they haven't bought at 30k level. Not only a month (about couple of weeks ago) and you are already earning good profits if you bought it at 30k level. Crypto market is really surprising us, no one can exactly know what will happen next.
