I'm not sure I understand. You're saying you got into Bitcoin very early and sold far too early. Now you're into Steem early as well and are holding your Steem tokens on Poloniex so you can - uh - sell far too early again?
Why not hold them in your own wallet rather than trusting them in the hands of a third party? Exchanges get hacked fairly regularly so why not be sensible and take care of your coins yourself?
