I think it's reasonable since bitcoin have high value and ever reach as high as gold so whenever who invest into bitcoin , they already made a great choice for their future investment.
By seeing bitcoin value based on graph , bitcoin become the great investment I've ever see compare gold
When the bitcoin started we were all talking about a new currency that is going to change the whole idea of using the money on the internet, but after a couple of years the price was really high that it has become more of an investment and people saving and buying it, and the ones who believed in it a long time ago are really lucky. I am not finding any wrong with them.
We cannot argue that we should not save bitcoins as an investment. It must be a basic human right to do what ever they want to with their wealth.
But time will enforce them to start using their savings. How long one will sit and watch their saving's value goes skyrocketing. Either their basic needs nor emergency needs nor emotions will make them to come out of their investment mode.
