3 year investment, copy trading on E-toro

Hello. Greetings from Denmark.
Nice forum you have here. I’ll be spending some time here in the future.
I would like to copy people on Etoro.
To minimize risk, my plan is to invest in 5 different traders, and not just 1. Traders with healthy statistics that have been able to make something like a 15% yield of their investments.
It automatically copies their trades, but I would set it to automatically pull out if they go below 70% of what i invested in them (if they loose more than 30% of what i invested in them).
I’m not expecting to necessarily get a 15% yield of my investment, but i feel that anything below 10% per year, is hardly worth the time and risk.
Is anything wrong with this plan of mine? Am I in for a rude awakening? :smiley:
I hope my rookie question make sence :slight_smile:
Best regards, Jonas

Edit: My plan is to invest for at least 3 years, but I’ll keep it going if it turns out to be succesful.
