Sent unswapped tokens to exchange and they don't appear.
I acquired 100 tokens in early 2018 and have done nothing with them until today when I sent them to KuCoin. The tokens are listed on Etherscan at the KuCoin address but do not appear in my KuCoin balance. Typically that exchange registers tokens very quickly.
I see that in February 2019 ([https://medium.com/theta-network/theta-network-mainnet-launch-and-token-swap-faqs-9a4bca3fb57d](https://medium.com/theta-network/theta-network-mainnet-launch-and-token-swap-faqs-9a4bca3fb57d)) there was a token swap. So I am wondering if that is why the tokens do not appear in KuCoin.
Will only swapped tokens be registered by an exchange? Thanks.
