So that can't be compared to Bitcoin which is an asset that has high volatility and in most cases it chart has moved in a particular direction that has perceived to be more up trend than a downtrend and what that mean is that the possibility for Bitcoin to make uptrend price movement is higher than the possibility of decline lose price. So ultimately Bitcoin is a more favorable investment tool compared to bank savings
You can see that there is no general approach to this, there are times that Bitcoin will perform well and the investment would worth it (strong bull run moments and season of long-term bullish trend) and there are times that Bitcoin will frustrate your investment (long-term bearish trend). As an investor, one could invest in Bitcoin during the strong bull run season that is long-term, and invest in the bank or elsewhere during the long-term bearish trend.
After all, this is a win-win approach.
