Bitcoin is about freedom and free market
Do anything you want to them, spend, invest, store, or something else
Things will correct themselves with the free market
I agree with this. Though it sounds so selfish but still it is you who will decide it. They cant say it is against the rule of bitcoin (if there is one). I can gamble or invest it or even store it for a long time then they should not care about it. Only those who holds a lot of it will have that very much effect but with little holders there is not much of a impact.
bitcoin will turn into useless currency its essence If everybody would just store it, people will always continue investing in bitcoin and use it for speculation and or trading.
