I think that the bitcoin is a good investment.. its just going to get more difficult for the miners (heard its supposed to be really difficult starting this fall for some reason)... This is just my guess. Ive seen it stable for the past few months and it keeps going up.. My guess is that it will continue to keep going up (lets hope) Ive heard that a lot of new tech. etc. will help the bitcoin grow.. its still very very volitile, but we shall see...
