Exchangers are scamming now!!
Nobody Can't earn money anymore bots are all over Exchangers!!
I mean, why you did not leave after knowing that those exchanges are using bots? If you ever find trading bots on that exchanges that leads you to get nothing, then just leave it immediately. It's not worth it to compete with bot, you just lose your money anyways. If more people go to that exchanges and give it more exposure, it won't die later.
