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.
There are lot of advantages and benefits of bitcoin in the long term. The most attractive one is the high margin of profit because if I hold my bitcoin in blockchain wallet and wait for long time then the price will be very high and I will earn a huge amount of money, due to which I can buy all the necessities and luxuries of life, and I will do it because I am waiting for a high rebate of bitcoin in the future.
