And that's quite a long post! Are IAD and DAI two different bananas or they're the same? Or was it the three minutes?

Anyway, here's my short story. I once converted a little amount of ETH into single-collateral Dai which was called Sai at that time. I invested it into something which offers around 8% APY. I let it sleep and forget about it for a while-- less than a year actually. When I checked it several months later, I cannot convert it back to ETH anymore because it was the old Dai.

While I was away for months, the old Dai, which was called Sai, actually launched a new version which was the multi-collateral Dai which is now called Dai. For some reasons, the information didn't reach me. Because of that, I wasn't able to convert my Sai to Dai during the limited time the conversion was allowed. To make the story short, my Sai are now worthless.

My point being is that this seems worse than inflation, even hyperinflation. Developers may rename or change tokens anytime. We have seen it countless of times in the world of shitcoins. They would give a few months for the owners to do the conversion or swap before the old token becomes completely worthless. If you miss that allotted time, your value would suddenly turn to zero. Now, that's more dangerous than hyperinflation!
