I am worried that they discovered their Cryptsy Points calculation was wrong (i.e. they were depositing too many Cryptsy Points into accounts).
The more I think about it, the more likely I think this is.
Based on
https://www.cryptsy.com/users/cryptsypoints:
How Many Points Will I Earn?
Each point has a reward value of 0.001 BTC. You will earn points based on 4% of the trade fees collected on your account. You will also earn points based on 1% of the trade fees collected from your referrals.
So lets say you paid out 0.1 BTC in trade fees in a given day and you had 10 referred users which also paid 0.1 BTC in trade fees each on that day.
Points Earned Directly 4 CP
Points Earned from Referrals 10 CP
Total Points Earned that Day 14 CP
40 CP corresponds to 1BTC in trade fees, or a turnover on an account of roughly 400 BTC, assuming an average trade fee of 0.25%. Scaling these numbers up to my account, I get what seems like a totally preposterous turnover, which suggests something is amiss. If there's a mistake in the above calculation, someone please point it out!
