According to Dynadon email:

Dear XXX,

This email is to inform you of an upcoming price change for the .ONE domain extension. The central registry has notified us that a price increase will occur on December 1, 2022 00:00 UTC. As such, our prices will be updated to the following:

Regular Pricing: $14.99
Bulk Pricing: $14.50
Super Bulk Pricing: $13.99

Please note the price changes apply to registrations, renewals, and transfers.

You still have time to renew your domains for one or more years with our current low prices. You can also transfer your .ONE domains over to your Dynadot account before the new prices go into effect on December 1, 2022 00:00 UTC.

Best Regards,
Team Dynadot

The current Dynadot .one price is: Registration/Renewal/Transfer: $7.85

I have just removed greedy Dynadot, .one Registry and .one tld from my domains list!!!
