According to observation, I think we are at the bottom and now and there are high chances that the price of Bitcoin might go upwards in a few weeks.
The last time Bitcoin cam this down, the next few days BTC went upwards quickly. So I believe that the price might soon cross $7500 in a few weeks.
We should hold our coins tight in this critical time because sooner or later the correction will end we will see a spike soon.
Well though the price right now has stayed a little above 6k, it did drop to 5.8k after this post. So i don't think we can say we've safely hit the bottom and would rebound from here. A lot of fingers are crossed since that is already the new all time low for 2018
