I signed up with Web3otc (web3otc.net) from a review site like this one and the first red flag was the aggressive account manager who would not stop calling. After depositing, the promised support vanished. Withdrawals are delayed with endless excuses. I have reported them to the regulator.
Pros: Wide product range|Easy to use platform|Transparent fees|Clean UI
Cons: Website design could be more modern|No phone support on weekends
