One time tested approach is when you get a double, take out half and let the remaining 'free' shares ride. Since you got in early on these cryptos, you have that luxury.
I'm curious about your strategy with the trips/penny stocks. Do you do a lot of fundamental research on the companies, or alternately, just pick a group of flat-lined penny stocks and wait for one to take off, and that big winner makes up for the others that don't do anything?
I've owned some sub $1 stocks, even down in the .10 cent area, but always figured most sub-penny stocks are unworthy of the required research. But gold is where you find it, and ONCI sure turned out to be a big winner :o)
