Eos in my Eth wallet

I bought some EOS, at the time they were ERC20 tokens, then came the main-net and they transferred to that automatically, I later withdrew from EOS main-net and sold them on an exchange, this shows up on that exchange.
In my ERC20 wallet it still shows the EOS but with no value, should I mark them as lost? Or are they burned? Please advise.
Also Minearium 32,000 should these just be deleted?

Hi, yes you can sell them for zero value (by creating a trade). Soft delete the Minereum airdrop.
