Why does the whole criptomarket fall? 
go mass correction.
Normally, when the price of bitcoin and other alt coins are pumping too much expect that there will be a mass correction and it will be followed after a week or two. go mass correction.It's known that many are contented with that price and many are starting to sell at that rate.
And you should be able to understand that the market is up and down, not all the time we are all in the green days.
I don't think there is nothing to understand and all because people be in the forum may already knew that bitcoin price is fluctuate always and it is up and down continuously. From this year starting onwards we see bitcoin price moves up and up again. Now correction happen, if you have enough fund means invest and buy bitcoins now to get the big profit.
Everyone here isn't updated with what's happening in the crypto market and it's unexpected that there will be some bad news rotating all over the internet.
First the China, next Jaime Dimon and what will be the next?
I hope that next will be the good news that will come out and this will make the price of bitcoin higher again.
