Bitcoin were good if you save it for long time, because bitcoin had a high possibility to up the price/value in the market place. Even from now it was fluctuating I was still believe that it was getting high in the future.
It's why I keep on saving because I experienced by myself that if I'm going to hold bitcoins any further this is going to give me an assurance that it will give me a better life in future. And I managed to have while the price is lower at $600 and right now, I can see that the price is really good, so the more bitcoins you'll hold the better.
Saving bitcoin for future is a good thing to do but I will not hold them for a very long time as there is no guarantee that price will go higher in future so I will prefer to sell them when its giving me enough profits as I can buy them back when price drops again in near future.
