I'm thinking of opening a few exchangers of cryptocurrency and other electronic currencies, but I do not know how, are there such people among you who have been in this business? Can I have a word or advice?
Running an " exchangers of cryptocurrency" requires a large amount of money, experience, legal advisors, marketers, development team, security and protection team, customer service team, this team must be homogeneous and work from scratch on developing the platform.
Therefore, your question indicates a weakness in one of the teams above, and this weakness means that the probability of your platform failing is 100%.
Try to run a peer-to-peer trading activity on one of the platforms.
