in 2 or 3 days from now the price will be back to normal because ,in my opinion a lot of peoples are scared not to lose everything . But it is not a good thing altogether because it will decrease the number of cryptocurrency holders by 5% -15% maybe more ... tell me your opinion about this . 
I don't think that the total number of cryptocurrency holders are going to decrease. Most people are in this for the long term so they really can care less about where bitcoin is headed in the short run even though it does matter too.
The markets overreacted to the news tbh. The central bank of China was already extremely anti-crypto and this wasn't necessarily a surprise. Altcoins such as ETH should have been worse hit and bitcoin probably less affected. This is the main reason why i think the recovery is currently taking place.
How much it can recover is up for debate. Personally i don't think that wewill make a full recovery as in continue the bullish trend that we saw that nearly pushed btc over $5000, but we'll definitely stabilize at around $4300 at least.
