Somebody placed a 250 shares buy order at btct (> 1000
BTC)

I'm curious to see if it is manipulation or not...
If that's for investment and not speculation then that person will be banging their head against the wall when they learn of DMS.SELLING. Costs 0.031 BTC per share and will be paying out around 0.008 BTC probably on Friday. Those 250 shares at 4.27 BTC each could purchase 34,435 shares of DMS.SELLING at 0.031 BTC each, which would make 275 BTC by this Saturday.
