i have also swapped Staked Eth to usdt when i was trying get stables to fomo into one stuff,

i didnt check the warning, i clicked max and clicked swap. I lost over $2k in that transaction. i realised later after the swap.
In decentralized world, you're your own bank, and transactions are irreversible.
Don't say it can't happen to you, because it can. just that it won't be $50M, cos who dash you lol
