So , what's going to be next? Up or down? Is it worth to buy BTC now and hold it for quite a lot of time? How do U think?

You might make some in the short run but my advice would be to SELL SELL SELL. This bitch is going to crush so bad you will be biting your elbows.

Based on your lousy, throw it against the wall and see what sticks, totally wrong previous predictions I think I'll buy a couple today.
