How about only earning Bitcoin and not using them?
I think the price of Bitcoin will gain much more value.
So if we keep it as our asset we will be much rich in the future...hehe...whats your opinion about this?
That can be Yes because of the potential of bitcoin. As long as you have the patience in holding bitcoin then why not, for it will boom in the future. Bitcoin holders are getting richer if they control themselves to hold it. But you have to consider also the possibilities that online can do just like hacking. People nowadays are becoming greedy, although not all, so you have to be extra careful also as to where will you keep your bitcoin.
