I save 2/3 of my bitcoin and waiting for the raise. 1/3 left i exchange to money or invest in something which are profitable. Bitcoin not my main major, i do bitcoin stuffs to earning money and invest in it when i see bitcoin can earning money and i get profit from it. However, in future, my plan of spending will be changed, all thing depend on how bitcoin will be in next few year, i always hope bitcoin will go far in future because i believe in bitcoin and what it can do !
Everything obviously balls down to what becomes of bitcoin in the next few years. Not everyone can keep holding for dear life for so long. A time will come when the value has increased hugely and one may need to want to diversify into some investments either offline or online.
For now though, I hold some of it since my job is centered on bitcoin earning mostly, being a freelancer, but I try as much as possible to save a lot by sacrificing something now for the long run.
