Nobody expect bitcoin able reach more than $ 15.000 / btc but it's really happen !
As we know, crypto value depend on supply and demand , that's why the value is too volatile, change drastically even less an hour.
You must aware and understand the risk before try to trade because if you want to achieve something big, you need to do some effort !
Bitcoin reached 20,000$+ within a couple of months that time it was surprising.
Than bitcoin dropped time was unexpected and a lot of people lose money because they invest rising moment.
So i think in crypto you should be prefer every moment to take risk.
