Basically, staking and unstaking are an on going process throughout the life of a blockchain and in EOSIO we have
0.1 token not 10% of the account's tokens is staked for RAM
Cleos stakes 8 KB of RAM on account creation paid by the account creator
0.45 token is staked for CPU
0.45 token is staked for network
My question is, is it possible user stake and earn reward without using CPU and RAM
as one of the main issues in EOSIO based blockchains today is the cost of using the network and CPU resources.
