You want a salary i think, by reading what you are saying. You want every month profit about 15k $, that is possible, if you are genius and have 100% luck. There is no right time to cash out, everyone search for it, hope for it, but there isn't. Read news about that you put your money in, make your own percentage, like 30% above your investment if they grow and you don't believe in them, pull off and invest in something new. Everything is beliefs and hopes, charts, but you need to make your own.
