No, you only need the coin. Im currently staking 2 coins. 1.st honey they need to be on your wallet for 6 hours before staking. Just keep your wallet open and the prosess is automatic. You can mine at the same time. You are staking against the network so more coin you have more likely you are going to get the reward the reward is 2 coins and its gonna allways be 2 coins. 2.nd is paccoin which need to be on your wallet for 30 DAYS but the reward is supposed to be 7-9% of your coin holdings. BUT my current understanding is that after the initial 30 day waiting period you have to keep your computer staking for 30 days to get the reward. If that is the case im not going to bother because paccoin is going to be gone by the time i get to the staking part
...the old pac is going to be gone i mean.
