I think that's more on investment now due to lack of either physical or better alternatives for online stores that accept bitcoin. But here in our country we are already using bitcoin as currency sometimes, when paying bills and mobile load recharge, so it is really usefull for us.
even if you can pay in stores with bitcoin i don't think people will start spending their coins. they are probably too worried that when they spend their coins, that the price goes up afterwards, and thus they will miss out on profits. that's how people look at spending their coins. the intention to use it as a currency gets overpowered by the investment aspect.
That's correct, everyone is looking to make good profits from it and that is the reason they won't be willing to spend their coins and will prefer to hold them for long term.
