I like PrimeXBT's Convesting Option. There is an opportunity to invest in strategies of several traders at once, very convenient management. I'm also glad that payment is only for profitable trades and you can unsubscribe at any time. Sometimes I had serious setbacks, but I managed to diversify my funds and now I can offset some traders' setbacks with others' profits. I am constantly watching the trade and learning to trade the market myself.See full review
