There are many low-key cryptocurrency exchange in this space, in fact there are many more low class exchanges than you can ever count due to the ease of entries into the industry. My best advice is to stick to the big and popular exchanges are let the low class exchange grow to avoid loss of funds. Its always very painful to get ripped off from an exchange. It hurts really bad, I've been there.
Frankly speaking, it's not that easy to create a good impression in very short time. BitMax done that, i see more and more people talking positive about this exchange.
