From 20 per month, now just over three per month... WLD is a model that accelerates the decline in earnings, and the current return on the 500 locked positions is still 10%. As human beings in each node, this is actually the most decentralized mode... The current number of registered users is still increasing continuously, faster than I expected the decline. When we reach 100 million registered users, each person will have less than one per month... I don't know when there will be an increase, but what I do know is that BTC undergoes halving every four years, while WLD has already decreased by 88% in a year...
