To every fall in the price of bitcoin, it ends up to be some bitcoin price corrections, cause after that, bitcoin stabilise and continues to rise. So, bitcoin falling to $7k/$8k might not take place anymore, cause it's current price will only fall to $9.5k and rise again.
Yes we won't see that low price of bitcoins now and even if people start dumping their coins and if there is crash in the price I don't think it can go below $10k so waiting for that price to buy is a merely waste of time.
