there is a large range to grow here according to some traders. a friend of mine invested cca 15btc. and he will sell @0,001. and he makes a living from crypto trading. and i dumb ass invested only .05 btc 
I think QUA is going to be really strong a liquid asset, especially with it's unique deflation feature. As far as the .05 btc investment, it's okay-- we all speculate and leverage within our own personal risk acceptance.
