I have a very simple strategy. I invest in ICOs I like and then try to hold long term, min 3-4 months. This was my hair is not turning gray and I have the potential to make decent profit. For major coins like btc or ltc, I'm keeping certain budget unless some other coin shows up where I see enough potential.
I do not even know, and how you have a result, from what I know so to do now is no use at all. It's easier to bathe on etherdelta coins, or just sell x2 when you go to the stock exchange if there is a stir and then reboot.
