I didn't participate either. Slowly but steady I am moving away from Ethereum and all Ethereum tokens... who cares about them and their crazy fees! I play, just not with them anymore! So I will wait for some next promotion, I don't doubt there will be one very soon... it's Betfury!
And I agree BFG tokens are too valuable to lose them or to spend them on bidding! At least for us here... maybe some high rollers are mining like crazy, so they can spend some here and there!
Maybe in July with the EIP-1559, the fees will drastically drop again which would make it again interesting to play more with ETH tokens.
I am waiting for altcoints spring part 4, which will hopefully bring some extra higher marketcap altcoins such as LTC, DOGE, XRP, DOT, ...
