if you want to hold onto your burstcoins that is your choice, but it should depend on how much you have invested. I don't have any burstcoin yet, but I too am interested in the system and tech behind it. It is a very unique approach to "mining". It could go down 20-50% more, or it could go up from here on, it's hard to say for sure. If you have a lot invested and are worrying about it, maybe put half or more back into USD. It's like they say "Never invest more than you're willing to lose"
