I, Dennis Spiess, left Germany in 2016 to become an location-independent entrepreneur. I have studied Business Informatics and could have somehow survived with software jobs. But I started with only two months worth of savings. Reason enough to look again into an investment opportunity I have already heard of a few years ago. But, unfortunately, I just didn’t understand it before. Now, I dealt with that topic again for a while not expecting that it would become a mainstream phenomenon in 2017 which sustains me financially until this day. I talk about cryptos.Cryptocurrencies? Aren't these those Bitcoins? Yes exactly! And by the way, probably the biggest technical revolution since the invention of the Internet, maybe even its true and full maturity.Did you ever want to deal with the subject of cryptos?
