I found this token that got airdropped on me a while ago, and I don't want it. It was valued at $18 or so.
I decided to sell it, but the exchange had a minimum amount, so I simply bought more so I could get sell the larger sum of the token.
When I tried to send trade back for ETH, the transaction failed. According to etherscan.io, it was a
SafeMath: subtraction overflow
I did some digging, and tried to use the approve method to allow myself to spend more. No good, the same thing happened.
Then, somewhere I found that it might be the contract calling the method, not me. So I gave the contract an allowance.
This is quite frustrating, and I'm already down $40 in transaction fees. I just want this pain to end. How can I get this transfer method to just work?
