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
Bitcoin can be very promising again this year so your advice to not sell our bitcoin is very a good advice, all te holders of bitcoin will get a lot of money if they will continue to hold and we the holder can have a huge profit if btc price will be $19k again.
