For stock like BTSC, BTCS, BITCF, MGTI, SING. All the sorkc price spike for 2-3 days with the catalyst that of north korea missle testing. Looks like no supporting for the stock. I will not chase given the price is already high.

 

I will leave LBUY, NSRPF, AMFE and TMQ alone, given no catalyst on those stock. 

For DRYS and TOPS, I did not see any catalyst for the spiking, maybe it is just short squeeze. I prefer to leave the stock alone. Only short or dip buy is available.
