2018 DAI is a 1:1 recent copy of bitshares stable coins that were operating since 2014 and handling drops of collateral up to 95% in the past several times.
If you would have asked me in January if I thought Dai could survive a drop in ETH to sub $200, I probably would have said no
This is just because you clearly didn’t know alternatives.
Funny thing is bitshares stable coins are far more used, and do not rely on centralized trusted liquidation triggers — the only thing dai added to bitshares design is more centralization.
and DAI oracles have virtually no money at risk
there are no intelligent people working on centralized ethereum in any manner.
