Well I assume it's still the ERC20 token I possess else I would be able to send it to HitBTC. That means I've spent about $4000 in Ethereum at that time,
and now you are telling me it vanished for good? Or is there still an option to switch to the ERC223?
Keep your question! I have a small amount of these tokens in my ers20 wallet. I did not know that it was necessary to swap tokens for erc223. What should I do now?
