I already have a lot of satoshis lost around several bitcoin exchanges. I can't withdraw those satoshis because they don't even worth the fees.
Like me there's thousands of others in the same situation which would make a lot of BTC. So I take it that exchanges keep these satoshis for them.
What do you think? Should exchanges be responsible for the fees and return every satoshi to their owners?
If the time it takes to return the satoshis is not worth the reward to do it it wont happen. I should imagine many people are the same as you i know i have everal exchanges with small amounts on which i likely will just leave forever.
