For me investing is good than to save. Because investing is to gain or earned more money than savings just like bitcoin if we invest money in the bitcoin our money came up double or triple than savings.
In bitcoin even we are just going to keep on saving it, the price will tell how much you would earned from that. Unlike in saving of real money, there's small interest if you will save that to the banks but still it's not that satisfying upon saving to them. So, for me it's better if you are going to do both things, they are both profitable.
Definitely saving bitcoin will give us huge profit since it is inclined to price increase. I also believe both savings and investments are good that we should do both of them accordingly. The only good thing with holding is that you control all your money while investing it will definitely be used by other people.
