Crex24.com is the best exchange even if they have low volume/low yenten for sell/buy and even if they cant be reached from North America (or by using a vpn)

Stock.Exchange is not the best (deposit/withdrawal take sometimes serveral hours, sometimes page goes unavailable or wallet goes maintenance ) but have many Yenten for sell/buy and is listed on coinmarketcap.

If i have to place a trade to sell or to buy yenten, i will use crex24 for sure. (even if it can take time for my order to be filled)
