We've been in contact with Bittrex and they should be upgrading soon also, and we messaged the block explorer owner a bit ago.
Are you paying for the bittrex add and if so how much?
We've been on bittrex since April, we had a pretty big launch with Ethereum devs and other crypto world personalities tweeting pictures of themselves as Pepe with our logo as a watermark, was good times. We couldn't get any bigger exchanges to list us as PEPE so we are also Memetic / MEME, but hope to be listed as both on other exchanges.
