I believe many of $IO economic models are great.
Out of a total of 800 million tokens, 500 million are released online.
The remaining 300 million are mined over 20 years, with tokens unlocked every hour for GPU suppliers
and token pledgers.
The release rate starts at 8% in the first year and decreases by 1.02% each month, with distribution expected to take about 20 years.
According to official information, the initial circulation is roughly 60 million tokens, with pre-computing power mining airdropping 15 tokens per machine.
So in my opinion it is a very good project especially because of circulation supply locked.
