It started before you even knew it. The bear market has started, but that won't make the price of bitcoin fall very deeply. so far bitcoin's resistance point is at 30k, and it's been a few weeks it's still holding up. this proves that bitcoin is still quite strong. maybe this situation will last a long time. bitcoin will go up and down between 30k to 40k.
So far resistant point is around $30k and in case of going below this point $25k can play the support line role. Unless something bad happens, market is not going down below $34k and the chances are higher for upper side direction of trend compared to downtrend. I will go for altcoins instead of trading flat market BTC price.
