I'm holding my bitcoins until they have a ridiculously high value - that is, until they have mainstream adoption and are used by everyday people consistently. I learned from losing money by trying to day trade and gamble. Believe in the technology people, not the bubbles.
That's true looking at the present scenario I hope that the prices will reach to the moon, as the prices are continuously going high in last month and it has almost doubled in last couple of months. So I believe that it would still go higher in the coming months, but this is the right time to sell part of bitcoins and make profit out of it.
