I've decided to do that by myself, trying to earn $10-$30 a day with margin. It's hard but I think it's good to get extra money in your spare time. I'll probably focus on this too if my other job is not working quite well.
Trading cryptocurrencies is a very profitable business, but only for patient people who are able to devote time to market research, technical and fundamental analysis. Digital asset trading is a process that provides a unique opportunity for a profitable investment. The main thing is, among hundreds of cryptocurrencies, being able to choose the right asset for investing money, otherwise, all expectations may turn into disappointment.
