I'd ask freeworm, who seems to be part of BTER staff, to post here all the trades done by the attacker.

I renew the request, this would be just fair and transparent.

The block chain is the main innovation of Bitcoin. It is the first distributed timestamping system.

Length of chain does not matter, it is total amount of work (listed as log2_work in debug.log file) done on it that matters. Put differently:

99 blocks mined at difficulty 1
1 block mined at difficulty 100 <--- this chain wins

TRC hard-forked at block 175,000 but last checkpoint is still at block 110,197 which means attacker still has coins he generated during attack.
Given that he also still posses massive hashrate, much more than 51%, he can still double-spend his coins, orphan anyone else blocks and so on.

So, does 101 blocks mined at difficulty 1 win over 1 block at difficulty 100?

Hi there. I trust you upgraded to -48 in time before the mandatory block to avoid this happening again? I put in a support ticket ahead of time to make sure your staff knew another mandatory update was coming.

Since TRC is steadily rising and my deposits don't even show as pending, I'm worried you forked again without installing -48 in time. I've let support know (well in advance) and mentioned it on Twitter. Not sure how better to try and get your attention when you and customers are at risk of losing money again...
