if you do not use them, willing to use exchange what? because the average exchange not licensed. if you have a licensed exchanger then let me know. Thank you
coinbase is a licensed exchanger I guess! they have also an american USA headquarter.
They do probably have a license, or as close as you can get to one if they don't directly have one, since they ask for so many identification pieces and various forms of confirmation.
if you look around enough though there are a fair number of licensed exchanges, you just have to go and find them because most of them won't be advertising themselves.
