I think if we save Bitcoin for a long time there is a chance of its fluctuated nature. So if we invest bitcoin instead of saving this will good. If we are risk taking personality we should save it for a long time in wallets. There are so many reasons to save it for a long time if we have huge amount of bitcoin and its price goes up there is a chances of growth in profits.
that's the only thing to do if you want to invest with a small risk, but sometimes it produces big, just save in a few bitcoins only, save in a few years can be profitable because if viewed from the charts bitcoin in the market it is always repeated, so save bitcoin in a long time it indeed still profitable
