The payout per block decreases over time, and so will the the annual inflation rate slowly decrease
towards zero. The demand for fungible, digital, privacy-oriented hard money will likely skyrocket
in the next few years and outpace its inflation, so investors expect a considerable rise in prices.

Nunca houve uma pré-mineração em Monero. Isso significa que ninguém controla grandes quantidades de moedas, uma vez que todas as moedas geradas

O pagamento por bloco diminui ao longo do tempo, e também a taxa de inflação anual diminuirá lentamente até chegar a zero.
A demanda por dinheiro fungível, digital e voltado para a privacidade provavelmente disparará nos próximos anos e ultrapassará a inflação, fazendo com que
provavelmente haja uma apreciação desse ativo.
