Technically we haven't had a bear market ever since June (and I'm being generous). What you have seen in the bitcoin market has been a third type of trend that is neither bull nor bear. It is more like accumulation phase where price goes sideways meaning it drops to $20k then it rises back up to $25k and repeats it many times until it breaks either price and enters a bull or bear market.
What do you think will help to help boost the mindset of investors again after all the ordeal?
Those who think twice about buying bitcoin just because of some volatility should not buy bitcoin at all because they never understood what bitcoin truly is. Otherwise those who understand Bitcoin, the decentralization, the only hedge against inflation, ... and most importantly have looked at the historical charts don't panic with each bump on the road or the FUD in the meida.
