I have started trading small vol coins, which were spiking or going down a lot, high volatility, that way I raised my capital almost 5x, in few months. Then I slowly moved to more liquid coins, and then spread my capital into 10-15 coins, in smaller positions, so risk was kinda diversified.

Now I am still trading some small cap coins, but mostly I like to go into higher volumes coins. And ofc always having cash, if good quality coins at a discount price, I m usually grabbing more of them.
In my blog (my articles) I am commenting some of my trading moves: almost every day.
