After for about eight months with BitnomicAI (webtrader.bitnomicai.net) I requested to close my account and withdraw. They said I had to complete a 30-day cooling-off period. Then they said there was a minimum holding period for my last deposit. They make it as hard as possible to leave.
Pros: Clear documentation|High security standards|Reliable uptime|API access
