Correct me if I'm wrong, but the impression I get after reading your whitepaper is that you're akin to trustwallet-PCS and metamask-Uniswap? Or is there an extra thing that I need to know before I ask further?
You can say that we're a binance dex, in binance you find everything you want incuding trading, margin, derivatives, nft, launchpad.
In Protocol X you'll find all those things the only difference is that we're fully decentralized and binance is fully centralized.
Sorry, but I ends up getting confused because your explanation is rather not correct. You put yourself in equal to Binance dex, with a difference that you're fully decentrlized and they're not. But inance dex is not cenralized, tey're non-custodial dex --as the name indicate-- where you trade directly with other users using walletconnect or priv key. Am I wrong?
If I may just jump into my questions, as it is rather confirmed that you're indeed --at the very least, if not more-- caters the same service as PCS and their colleague, this is from your whitepaper:

Can you please explain more on these matters, about how those things are still a current problem, with each numbers represents your point on the whitepaper:
1. This problem is solved through PCS and other dexes with infinitesimal fees.
2. Again, solved through dex --PCS, uniswap, and even binance dex-- with their non-custodial nature.
3. If a trader asked about this, then they need to read more about the rule of thumbs in crypto trading: never put your money in an exchange, it's not your money as long a you didn't hold the key, etc. Which... also kinda solved by DEXes ans swapping platform. So what's your point here?
4. Yes, it is possible go get NFT, metaverse, defi space, and even perhaps meme token in one plarform. I cordially invite you to visit the altcoin token section on this forum. Spoiler alert: you'll be surprised.
5. Now, this is a recurring amd currently unsolved situation. But, what's your solution?
As for the section after it, the "solutions" you propose, I'll have to echo what
jc12345 said, zi didn't find something new on your solution. Literally all five of them are "features" that's been offered by tons of projects
