It is unknown. IMHO, we probably won't be seeing $20k again and the support has already been done on $30k. If you want to get an entry, this could be the right time.
It sits on $33k.
I heard it already before, people think bitcoin will not dump below $10k after it hit $19k because of the strong support, but we are all wrong, bitcoin even hit at $3000 level and with that, I can say that it's hard to predict the market.
If bitcoin hit's $20k, I think it's not a good entry point as it could dump lower as that's what we are suppose to see for a heavy correction.
Bet on your own prediction mate, I believe short term trade would work, if it dump a little, buy them and wait till it rise, I think we will see more of that before the price will eventually correct big time.
