Phemex lures people in . . . .
Phemex lures people in with promises of large sign-up bonuses, but there are very significant strings attached to virtually all of the offers (e.g., a requirement that you have to trade a cumulative total of $50,000 before claiming the advertised deposit bonus). Since they charge fees for withdrawls and other transactions, the "bonus" will end up as net loss, and you can't get assets out without paying more fees. Stay away from "Feemex" and stick to more established sites like Coinbase.
