Bitcoin is what you use it for! For some it's an object of speculation. For others it's a platform they can build their own businesses on.
Basically that. Bitcoin is whatever you want it to be. It's getting annoying with all these people that think Bitcoin isn't meant to be used for this or that purpose - mind your own business!!
and is going to crash if is just saved and not used, so the BTC will crash to zero very soon if that does´t change soon.
Hello noob. People saving/holding their coins, heavily contribute towards a higher price as they make sure that there are less coins in circulation. More respect to the holders, please... Don't forget that in current times, merchants make use of third party payment processors - which means that the coins people spend, will eventually get dumped on the market. In other words, more people spending, will result in more pressure on the market.
