Regarding the last value for USDE it might seems that it was between 5-7 sat per 1 USDe (more than 100$ per transaction). The last price that appears on coinmarketcap of 1 sat was because someone sold USDE worth of 10$ from 5 sat to 1 sat on the last exchanges that had USDE listed (maybe Alcurex).
1.9 USDe * 7 sat * $0.0000381293 * 1440 minutes/day = $0.73 a day for all miners
But okay, let's say 50% USDe of is unrecoverable which would double the value. Now miners get to share a whopping $1.46 a day. So what exactly is the incentive to mine this coin currently and in the future? For people who mined at 1000+ block reward and are holding large quantities of USDe they need to miners to keep the network alive, but for newcomers the reward is negative compared to the cost of electricity and hardware. So you're not going to attract any fresh blood this way.
I can't sympathize with your cause, because 1) I don't have a big USDe wallet and 2) the usde.co is updated but the old, misleading specification "block halving every 1/3rd of the coin’s total supply", which means 1000 USDe block reward, is still there and 3) feature-wise USDe is made obsolete by newer altcoins.
If 50% of the coins are unrecoverable, we aren't able for the moment to guess what would be the value. We will take in consideration all possible solutions for miners to come back. Regarding the current website, the coin specs were the initial ones. In september we're thinking of launching a new platform more oriented to regular users in order to attract them to crypto.
