The rewards for the REVA project's booster tasks are not very generous; completing all will only net you 50 coins, and later, 25,000 people will be drawn to distribute 100 coins. If you're lucky, you might get 150 coins, but the consumption is low, negligible really, and it's still the first phase, unlocked early. Spending some time on it is not out of the question.

The first three tasks are simple, just follow the guide tasks, and once completed, verify directly.
The fourth task begins, click sign in.

Then start entering your email to register; it should work with any email, I used QQ.

Enter the page, register an ID and bind X.

Scroll down to find the wallet, copy the wallet address, and recharge 2.5 USDC and some BNB for gas to this address using your Binance wallet. It's okay to charge a bit more; I guess the tasks in the next few weeks will be like this.
