Doesn´t matter if licensed by FCA or Cysec, the vast majority of them will deceive you one way or another. If not processing withdrawal requests, or executing your trades without mandate.
Pay special attention to those claiming to be 100% STP or ECN, they are not, the will deal you and stop you out.
One to avoid now, a CYSEC regulated that is about to go bust, Traders-trust ltd. Formerly tradingforex.*com, every two or 3 years they close down shop and reopen under another name, using the same license. If you are using that one, move your money now (while you can).
AVA FX is also having some liquidity issues.
2019 was a bad year for the industry, expect some more to go down in the European industry
