Strategies for introducing novices to web3

Salutations.

I have the use case that a lot of people completely new to web3 are going to use the platform. This novice user will register a wallet and may win prizes.

We would like to have them (the novice user) performing all the actions, there will be a couple of instances when they will be using the money they earned on the platform to sign transactions and pay for stuff.

But the point is that the novice user doesn't have any crypto to begin with. They will win their money on the platform. We don't want to have them going to a third party to buy crypto prior to accessing the platform, they have no prior knowledge and may be wary, this is a barrier that will stop them from ever using the platform.

As for now, the novice user can win a prize if they solve a challenge, this challenge is set by a seasoned user who has a different role in the platform. In this instance, this seasoned user sets a challenge and pays for its bounty. The creator of the challenge is the one to release the payments for a list of user addresses that resolved the challenge. So just by having a wallet linked to the platform the novice user can earn funds. This is the ordinary means for the user to earn funds. With this money, the user can sign/pay for other things on the platform.

The platform supports the coinbase wallet, so they could go to coinbase to buy assets there. The main thing is that they can swap the money directly on the wallet. They don't need to search where they can go redeem their crypto for fiat money, we're already pointing them to a place.

TLDR: brainstorming ideas to introduce novices to web3 other than wallet auth, using the coinbase wallet, and other things a dapp should have
