and then I can just send the HT coin to the HECO network and buy the heco coin wit the HT there right? I already added the networks thanks guys
Your HT token was based on ethereum blockchain and it can't be send to the HECO network as it was a native blockchain owned by Huobi. You need to bridge it if you wanna try to send it to the HECO network.
There are some solutions for that
1. Use bridge to convert your HT (ethereum) to the heco chain
2. You can create account on huobi and then depositing your HT token. You can withdraw your HT to the heco chain address directly from there.
