I just saw this picture of one of the traders celebrating that his account reached over a million quickly due to the short trades he opened today on Ethereum $ETH and others.

I don't care about this type of posts but it caught my attention that the leverage he is using is not too high even though his capital is large, and this is a lesson we should learn: no matter how much your capital is, do not use massive leverage.

The other thing is diversification in trades, entering a trade for a large currency like Ethereum and other trades for smaller alternative currencies.
