Really? WorldCoin has proven this? Which other coin has had an entire mining pool mining on an orphan blockchain for more than 300 consecutive blocks?
The problems were reported by miners; no one lost coins in transactions, at least none were reported.
Also, the pool that took over the blockchain (erundook's) was at about 90% of the hash power since pools just started popping up and his was the most popular. Ask him.
Okay, sure, you can't lose coins that weren't given to you in the first place. The point is that the network can't stay self-consistent with the given block time parameter.
