I'm no financial advisor, I'd simply say go with what you feel. It may or may not go higher, but one thing is for sure, never invest more than you can afford to lose. Considering your stake can be kept and used to vote and gain rewards, even if you lose in the short-term, it can be given purpose elsewhere to still produce gains. :) Remember, I'm not the best to ask about this and my only advice is to trust yourself and don't put up what you can't let go. :P
