I'm a crypto currency trader and i'm work around 4 years ago, when i'm start trading on that time bitcoin price is not a more than $2000 but bitcoin price is very growing it is hit around $20,000 but in this recent price is very dump, Now bitcoin price is around $8300 up and down very hastily, If you think bitcoin fall down i think your prediction will be fail.
You can see that the market is showing signs of uptrend in the short term, bitcoin prices are steadily rising in recent days and altcoin prices have also started to increase. Therefore, I think that for the safest of the moment, you should only be short-term investment and trading day to be able to minimize risk and profit safely.
