RAM/CPU/NET are resources of your account needed for interaction with EOS blockchain. You can setup it during the account creation if needed.
When you pay fees to create an EOS account, it means that you are paying for a certain amount of RAM which is required for the account to function.
It depends on how much RAM you need for your account, so the price differs but mainly it's 10 USD.
We generate a link to EOS blockchain once the account is created, so you will have a proof that now you own an EOS account.
EOS uses private and public key pairs for every account. If you don’t have public key we provide you with it and you need to save it in a safe place, However, MyWish is not saving any private pairs.
