I had set a limit, at which I would not buy any more bitcoin, but as the priced dropped, I felt compelled to buy more and more. I have lost more than 2 year's worth of salary on bitcoin this year and I still feel compelled to buy more. I am among those who feel Bitcioin's rise is inevitable, and as such I do not "feel" as though it is risky, but I worry that my behavior is essentially the same as someone who becomes addicted to gambling. I think its time to research and look for other promising next wave of crypto - i think AION is going to be one of them.
