Thank you.
Its not possible to stake any other coins/tokens in a POS model because most of the time they prefer the native token/coin to be locked up.
Does this mean, that there are the designers of the blockchain, that decide if only the native coin is available for staking and no tokens. So can you say any blockchain, that allows also to stake any token?
(Please note I am not talking about "Yield Farming" "lending" or "Liquidity Mining". I am talking about staking as validator or in a pool.)
