If you see why the btc keep crashing is because there is split/hardfork etc the investor has split their money into many places..
Just like when you see the btc crashing.. did you see all other alts? they all join the crash..
It's because they all investing using BTC not from FIAT!
If you combine all alts volumes into one volume then you will see the Cryptocurrency is rising like crazy in the past weeks or months..
When people realized this then people will start saving their btc more then all those alts that almost all of them starting showing signs of scam or has scammed peoples..
