Bitcoin dipped to 7500$ and i think now it is danger zone could go to 3000$-4000$ again.
Good chance for newcomers, sorry for those who bought bitcoin at 18,000$ an 11,000$ 
What do you think? How low bitcoin can go? Just hodl it
It's better to buy your coin with your spare money, because if you lost it, you still have money to buy things that you need. Just hold your coin, selling Bitcoin when it's no better than your buying prices is just wasting your time and effort in here.
