A lot??? Dont' be so sure
My calculations show, that to make a 200 BTC worth of BLOCK's "refunds" back into bittrex buy-wall, all is needed is to sacrifice only about 15-20 BTC.
That is $5-7K only. A lot on money for a a TEAM of SDC bagholders???
If someone wants (& I'm sure we have more then one such person) to make this ITO fail, all is needed is buy all BLOCKS at higher sell prices, in value about 220 BTC total , and dump all these BLOCKs back into bittrexs wall at 0.00025
At cost of 20BTC lost - this ITO can be ruined. I'm not joking, this is serious danger.
Too bad - we see so many BLOCK sellers in the price range of 0.00025 - 0.00027
Guys, if you want ITO to succeed - DO NOT sell even one BLOCK until bittrex refunding buy-wall is away.
Just STOP SELLING. AT any price !!!
You will see much better prices in a short time. Just HOLD those 2 days!
I think your estimate is low. It's probably closer to 40+btc. Once people realize someone is buying they won't put the sell orders so close to 25k and eventually there won't be many sellers left. You may be able to make a good dent though.
