they do - several do
(what you’re asking about are actually “funding companies,” not “prop firms”, though in this forum they’re commonly labelled and described as “prop firms”, and these days even some of the funding companies call themselves that, which is hugely misleading!)
there were - among others - a few people here who successfully traded with MFF (“MyForexFunds”), currently in receivership with regulatory litigation pending
i, like many others here, mistakenly thought they were one of the better companies to deal with - this appears probably not to be so, now (so be aware that whatever you read here on this subject is “opinion only” and mine - just like anyone else’s - can turn out to be wrong!)
big and complicated question
nobody knows with certainty
there’s litigation under way, which may resolve one or two issues, but there’s no guarantee even of that
my own answer is that most (not all) of the CFD/spot forex funding companies are NOT legit (i think FTMO almost certainly is, though, and maybe Lux Trading as well), and that most (perhaps not all) of the futures funding companies are legit and have to be, and that this can easily be verified (and certainly they include TradeDay, Topstep and Earn2Trade), and that the futures ones are - for many other reasons, too - a FAR better proposition
well, those are certainly the people they’re aimed at
there’s no point in paying for an evaluation unless and until you know you have the skills to pass it, and that’s easy enough to find out (with a fair degree of confidence, albeit not quite with certainty) on demo accounts anyway
the only way you really have anything to lose (other than some time/effort) by trying is if you pay to take an evaluation without having previously “passed” the equivalent, to your own satisfaction but under exactly the same “rules”, on demo a couple of times
if my opinion doesn’t put you off (my opinions sometimes do put people off, i’m told!), i said more on this subject in these posts/threads -
be aware, also, that there’s a malicious troll who has been banned under multiple aliases from this forum (and from at least one other, too) whose favorite subject this is, to “discuss” (he loves telling people that all “prop firms” are 100% scams, that nobody is ever successful with them, that nobody has ever been paid out, that all the participants have been “duped”, that all the evidence to the contrary all over the web is fabricated by “paid actors” and a lot of other idiotic garbage like this - it isn’t easy to argue rationally with him (in fact it’s almost impossible), one of the main problems being that some - just a very little bit - of what he says, regarding the CFD/spot-forex companies, is probably actually true!!
