This is an industry wide problem. You're right though, having an all in one platform is great for people new to the space. Especially bloggers that are coming over with little to no crypto experience. For those people, having to create a separate wallet will just be one more obstacle or deterrent for them to get signed up. Another reason to say, "Oh, it's just to complicated. I don't get all that crypto stuff". I've noticed everyone talking about new wallets but this is the first I've read about any of this. It would be nice if they had easy mode for new users and advanced mode for the folks who have been part of the crypto rodeo for a bit.
