Scam. Do NOT use Mercatox.I went to cash out, but it would not let me. Their system has been under maintenance for weeks.Customer service is useless and probably automated.Customer service says that they are working on it – day after day after day. They’ve been doing this same thing to people for years – just look at the dates on all the comments here. Somebody deserves to go to prison for this SCAM EXCHANGE CALLED MERCATOX. The exchange is almost certainly run just like a Ponzi Scheme. It’s hard to believe that they can continue on like this year after year without being shut down.
