How much leverage are you using?

In December, I put my bonus in futures and lost it in just 2 days. I kept trying by putting in more money and always lost everything, until this week when I returned with only $7.00 and have not had a single day of loss, thank God. Maybe they can question my methods of only trading short, but my results show that I am on the right track. I look for the coins that are on the winners list and trade those until I have small profits that at the end of the day add up to a benefit of more than 10%.
