In the last two days bitcoin prices are falling. Should I sell my coins or should I wait.Will the falling trend continues and we will be again back to $450 or something?
Buy more. If you've devoted time to bitcoin, then you clearly have decided to invest in it. If you're willing to follow that through to the future, then I would buy more and hold the bitcoins. I don't mean to hold until they reach an x dollar benchmark, no. I mean to hold them until you use them directly. After all, that is what we want, right? More adoption with merchants and consumers?
