https://koinify.com/blog/our-thank-you/Due to the unexpected downtime, we discussed with Gems team and they've graciously offered a 24-hour extension of GEMZ at the most favorable rate. This will make sure that everybody who missed out on purchasing due to technical issues can get another shot. So yes, enjoy another 24 extra happy hours at the 17,250 GEMZ per 1 BTC rate. This will extend 24 hours from 9AM PST, December 3rd, and ride into the price drop at 9AM PST, December 4th.
If you want to be thankful, stop breaking promise and go ahead on promised time-table.
They can buy gemz with next rate (who missed out on purchasing due to technical issues) according to selling time-table, that's decentralised project so you can not sit there and take decision for hol!
