I just saw this picture of one of the traders, and he was celebrating that his account reached over a million quickly due to the short positions 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 very high even though his capital is large, and this is a lesson I wish we could learn: no matter how much capital you have, do not use huge leverage.

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