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 resistance point is around $30k and in case of going below this point, $25k can play the support line role. Unless something bad happens, the market is not going down below $34k and the chances are higher for the upper side direction of the trend compared to the downtrend. I will go for altcoins instead of trading flat market BTC prices.
The resistance above $30k has been holding strong for quite a while now, but even if that breaks I cannot think of Bitcoin going below $25k. I think buying pressure would come up so hard with all the retail investors having the all time high in mind. Even institutions who got in this year are probably going to stock up at that price as they have a whole different perspective on return on investment. If they see the opportunity for 30 - 50% plus within one year, that is phenomenal for them. If it drops below $25k I'll stop with my predictions...
