I hope the market will grow up again after August 2017, because biggest speculation happen on that month. Actually, we can decide when the market will rise again, we don't have any control about it. That's why money management is necessary, to minimalize loss and make us not panic. If you have bitcoin don't sell it but if you're a brave trader/ investor, try to buy bitcoin, because today is the lower price. Don't buy so greedy, just with 20% from your money. Good luck.
