I like it, I appreciate an attractive interface, and I love how simple the transaction screen is.
It is a simple verification process, and the support was great. No, there isn't a great variety of coins, and I would like to see more, but if you're starting in the crypto-sphere or wanting to up your portfolio, then it's a great way to increase your holdings. I love the fact that I don't have to hold my funds on an exchange. Against big name exchanges the fees look high, but comparing like-for-like currency changes, they are on par and even low in some cases. The prices aren't the best, but I will trade that bit extra for having full control of my BTC.
I think this will be a great exchange, especially if they increase the coin selection.
Overall, I will recommend Terrexa to friends wanting to invest, perhaps not so much to my crypto-experienced friends. However, I would recommend signing up and verifying an account if only to see how it works and to have a handy place to cash-out.
