Callisto blockchain developers have announced the addition of cold stacking for a few weeks.
This will allow pool members to earn money by storing money in the account.
Cold stacking allows you to maintain a balance between miners and network members. You can earn not only on mining or difference of exchange rates, but also on the storage of the crypto. Income is calculated as a percentage of the amount in the wallet.
To make a profit from cold stacking, it is not necessary to mine Callisto or open nodes. It is enough to keep the cryptocurrency in your wallet.
