I guess it's not that hard to be able to maintain bitcoin for a long period especially of you know for sure that it's value will grow exponentially over time . It's like making an investment with 0 efforts , all you need to do is just wait and your funds will grow by themselves . Bitcoin is the currency of the future and sooner or later people will regret not onvesting in it .
Trees do not grow to the sky.
By what bitkoin is interesting except its growth giving the opportunity to earn? Practically nothing. Many altkoins are much better than it.
