I believe you can try to just simply change the current network into ETHW, then you can have it.
Just click "Change Network", then "Add Custom Node". There will be a pop-out to be filled, make sure you choose "Custom" on the "Network" dropdown.
Based on the information at the referred link above, here is the network information:
Network Name: ETHW-mainnet
New RPC URL:
https://mainnet.ethereumpow.orgChain ID: 10001
Currency Symbol: ETHW
Just adjust accordingly with the form that MyCrypto has shown. After that, proceed with "Save & Use Custom Node".
