Keep in mind the ChronoPower of each timemint halves every 88 days, but you can sell your DAY tokens without the TimeMint if you wish to do so.
What will happen in 2 years then? The ChronoPower will halve 8 times, but still generate some small amount of tokens (will go from ~0.5% to 0.00195%)?
That is what TimeMint was designed . So basically the longer TimeMints operate the lesser it yield DAY token. So better strategy is to buy more at the exchange as early as possibly to send the DAY tokens for minting before it half .
