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?
without any experience in trading, do you want to create an exchange platform?
sorry not to belittle, but it would be better if you try to trade on some well-known exchange platforms now before you do. so you will know how the advantages and disadvantages of each exchange. you can make it better on your platform.
the process will not be easy, you have to have people you can trust next to you and especially strong capital to help your platform compete with existing ones.
