I already read about upgrade Coss token to Erc223 in beggining this month.
I holding my Coss few months from 2017 year on Nano Ledger S like many people with any erc20 tokens for mid/long term.
But I today noticed that etherscan.io stop shows price this token (ethplorer.io still shows price). I check and my tokens are shows as old contract adress. Dont changed to new contract automatically.
So how upgrade my tokens to Erc223 I never do it before with any token. I only used Ledger Nano S with MEW. And I have some like 50 k tokens bought in december2017/january2018 on etherdelta and now I see it on etherdelta and forkdelta too but they shows old contract adress too.
So what happen and how I can (and I think many people who not read about this yet) update my all tokens both from Nano Ledger S and Etherdelta to Erc223 and new contract adress ? I searching on coss site/coss blog but never find guide how make this update. And my all tokens have few months old so are not bought after update as "old" or "unless" from etherdelta I have them from 2017 year on my Nano Ledger S.
