Investing your money into bitcoin is a big risk, a fall of 70% are normal in crypto currency. just give it some time, bitcoins will once again hit 20k and after that we will get a new all time high.
In the past few days, the market has been showing signs of bitcoin rupture and bitcoin prices have fallen sharply over the past seven months and are now heading at $ 6500. Bitcoin prices have fallen more than 70% since launching at $ 20000. Because of this I believe that at this time you should only invest the time and trade on bitcoin.
