It seems to me that what you've earned is not your merit. In 2017, there was such a period. Then all earned. Show your skills this year. If you're in this year earned on the investment of 80% of the profits I will say that you are the master.Lol!
let alone 80% to get 50% profit this year is very difficult. it is different with the year 2017 almost every person who is engaged in the world of crypto get big profits. This year is a verification for traders. for those who can get through this difficult time, I'm sure it will be an achievement
