I've read that it requires 2000 AVAX to run a full node, which stakes 13%/year. Does it mean that AVAX's total supply will be increasing by 13% each year?
Yes 2000 avax is required for the staking. Too bad I only have less than that so can't really do the staking only the delegates reward. Total supply? Or you mean the circulating supply? It does add additional from staking but not sure if this will be on total since they have a fixed supply of avax coin. Could be wrong, but let me check it.
