The only way to buy YZZ on the entire network is through staking, which reduces wear and tear daily. The current balance is about 0.3% and it is automatically purchased. Except for wear and tear, it can be withdrawn at any time. The 2% sales tax is automatically sent to the black hole address for destruction. It is permanently deflationary with no new issuance. Inviting others can share the daily rewards of the KOL prize pool.
