Any form of investment will also generate risk, and that's the fact. Ofcourse putting your fiat on hold will not create risk but will also not generate profit to put it simple. In the first place, it depends to the individual whether to engage in an investment or not. Bitcoin and other cryptos are having volatile market value compared to the majority of the stock market investment. But observe how popular cryptos are whenever there is an upward movement regarding their market value. The logic behind here is that, putting your money in Bitcoin will surely be risky but the higher the risk, the higher the chance to earn profit. But this is not applicable to all of the situations.
