yes, unfortunately that’s very much the nature of the industry
the more you see brokers depending on such methods of attracting customers, in general, the less likely they are to be properly regulated, decent, good brokers, as a rule of thumb
my own preference would be for Oanda, as i’ve only ever had good experiences with them
the most important one to avoid, IMO, is FXCM, who are outright crooks (as countless regulators have been saying, worldwide, for decades, while fining them very repeatedly indeed - and the US has even kicked them out of the country, now!)
but it’s all very subjective and difficult to judge, for sure
one little tip: FCA regulation in the UK is far, far better than CySec regulation in Cyprus
most retail traders use awful brokers: it’s one of the reasons the overall success-rates are so low, so even finding that out isn’t much help, really
