Can anyone explain me, where can I stake my MDX that is staked for 15 days in binance?
What do you mean by this? If you are staking in binance, then, it is in binance, right? Because you can't stake your coins again if it is already staking. You need to wait for the locked staking period to be over before you can fully redeem your coins. Can you explain a lil bit more what you wanted to convey here?
