Before we buy Bitcoin and invest it as well as we do first research on Bitcoin itself, and learn everything about Bitcoin deeper, always pay attention to market movements because we cannot buy when the price of Bitcoin is high because it is too risky.
Buying bitcoin as an investment can provide a big advantage, because the movement of the price of bitcoin is rising. This trend is usually long and speculators buy as much as possible so prices continue to be pushed up.
At the moment I suggest buying bitcoin and investing money that has not been used so far, HODL for a long time then sell when the price is high. This principle is the safest way to profit from bitcoin.
