I predict that at some point in the near future, we will experience a chain reorganization after 1 confirmation, and more than half of the exchanges will go down
1 confirmation seems like enough, but will you bet your entire backend on it?

This happens multiple times per year.
What?? I haven't seen this happen once? 😅😅
Orphan blocks happen when two blocks are mined at the same time. The block that gets a further block added to it will become the legitimate chain, and the other block becomes an orphan block.
It's the reason why Satochi said to wait for 6 confirmations to be absolutely sure your transactions confirm with near zero risk of being orphaned.
Having a chain recorg after one block happens. Having a chain recorg after 6 blocks is improbable.
