Tomorrow's price may be higher or lower than today, so there is no right or wrong time to buy bitcoin.
If you have free money now and want to start dealing with Bitcoin and the other cryptocurrencies, do not wait for anything. Buy the crypto right now, man.
The price is totally cheap right now and If I have some spare of money today I would probably choose to invest with bitcoin. Hey! this is just a short term dump, this is not forever so expect the price to rise again so better not to waste any opportunity right now.
