If you want to convert your YOYOW ERC-20 tokens to ETH you can also use https://ethersweep.com - It is very simple and it will take you 20 seconds of your time.
Here is the procedure you should follow:
- Enter your Ethereum wallet address
- Review wallet contents and quote.
- Assuming you are happy with the quote, first enter your output wallet address (I.e. this is the wallet that we will send your ETH to), then enter the private key for the wallet we are sweeping, in order to start the transaction.
You can also convert many other ERC 20 tokens if you have them in your wallet
