For forex and leverage trading in general, probably go with eToro[1]. I personally never had a problem with it. As for KYC, I really don't think you're going to find a legitimate and reputable platform that handles money without KYC.
-> Cryptocurrency accepts investment (I am also waiting for your service suggestions if you do not accept it, accepting other payment methods.),
What do you mean by this? If you meant that you also want a platform that you can buy/sell cryptocurrencies, then yes eToro also has crypto.

https://etoro.com/I know the e-Toro but if i remember it well, their commisions are too expensive to deposit and withdraw. Also i'm not sure about that but they don't accept investor from Turkey (but i'm not sure). For the quotation point, i'm so sorry for translation mistake. I did the correction for that part in my main message.

I'm not sure because of this, I can't remember exactly, but it seems feasible on Top1markets platform. I recommend it to you because I think it meets the standard you set; otherwise, just ignore my suggestion
. It is also a new platform, I am supporting them in some work, but certainly not advertising their platform
