You can join InstantAdPay with only your email at Member area | InstantAdPay. No wallet and no password needed.
As a free member you can view ads, watch videos, make verified visits and sign in daily to earn ad credits. Credits buy your own ads and are never cashed out.
Your wallet only comes out when you buy a package or switch on payouts, and the site walks you through it. POL (the actual crypto) is paid by the contract to your wallet when your referrals buy packages, once you are activated.
