Just to remind, PayPal is not crypto-friendly (unless you sell a hardware wallet with cryptocurrency on it and have a proof of shipping it).
It is not friendly towards any sort of digital goods in general (there had been many cases that someone sold eg. World of Warcraft very valuable account via PayPal, and soon lost a chargeback case against the buyer who then got back both money and had ownership of account).
I'm having a hard time too to transact whenever PayPal involved. I prefer to just use crypto or transfer via online payment that PayPal. And it's been long I tried to use other platform. We need to have our own strategy and see whether it's better if we use other platform if our skill isn't enough.
I've been using PayPal to move my Bitcoins to the other wallet and it all be fine but I'm not sure if we are using other than of Bitcoin. And I don't why it doesn't work with you mate. It may be because of the origin/or the place where you come from.
Wait, what? moving your bitcoins to another wallet using Paypal? When was this started? As far as I know Paypal does not support any cryptocurrency even with giant, bitcoin. And the only thing you could do with paypal here in crypto space is a wallet receiver for your sold crypto in coinbase, so that will be in fiat and has no problem with paypal.
Back then, accumulating bitcoins while in trading is not hard to do if you have enough money. A lot of platforms that could help us, it all depends on our preferences.
The platform would be helpful if the OP did not played it too safe for himself, everyone is right you don't need to be shy promoting the platform you were involve. However there is already a high competition in DEX, perhaps you have great deal for your potential users.
