If you look at both ME and Abraxas' wallets carefully it's pretty clear that they both exit scammed. The small amounts left in each wallets at the time of the shutdown is irrelevant. Looking at each of their histories on walletexplorer they were siphoning money out of their markets for weeks. It's almost like they were co-ordinated/the same person. The only difference is ME left the site up with the 'down for maintenence' BS and also emptied their wallet completely of what it had left after the shutdown (~650 btc) while Abraxas has left ~300 btc in theirs. Maybe that was to throw us off but I don't see how that even matters at this point.
To those wondering how much they stole, it would appear that about 35K btc was funneled from ME into this wallet: https://www.walletexplorer.com/wallet/008f9d8c0ab3d5bf. In Abraxas' case it is harder to track because it was withdrawn to a large number of wallets over a long period of time- but I can only imagine that it was even more, given that Abraxas was probably bigger then ME. But in total we are talking about probably more then Evo between the two of them.
EDIT: To those saying Abraxas' wallet still has btc, true but it's only 300btc/$100K. There's no way that was all they had. They were one of the largest markets. And if you look at the history on walletexplorer they NEVER had more then 300 btc in that account. It was constantly being moved elsewhere.
They left only to come back as 1 super market.
