Cryptomate is a UK exchange where you can purchase virtual assets . The exchange only allows traders to purchase virtual assets using GBP and so I don't think the exchange was created for foreigners ,only UK citizens can approach the exchange and buy virtual assets using funds from their bank account or sell their assets for GBP. The exchange's fees were damn too high for any traders with the consciousness of making profits because they charge a trade fee of 6.7% and the exact amount is charged for all withdrawals, to make matters worst the exchange isn't liquid and so it has only a few trade participants which will make it inconvenient trading on Cryptomate exchange and so I suggest UK virtual currency traders look out for other better digital brokerage since there's a likely chance that the exchange will shutdown soon.
