On Bter and Poloniex. Since the markets opened already and trading has occurred, how would those BLOCK be purchased back? Through a Buy wall of the collected BTC?
AFAIK there has been no mention of either of those exchanges intending to place a buy wall because, as you rightly point out, the market is already open and trading.
Bittrex won't allow anybody to transfer in BLOCK bought elsewhere while their 48hour buy wall is open, for obvious reasons.
Right, and I get that. I'm talking about if the project is not funded to a minimum, all BTC will be returned to investors. How will that work with all the other exchanges besides Bittrex?
From the ITO PDF, under the section "ITO Rules", it states: If an amount of less than 850 BTC (~$300,000) is raised, funds will be returned to investors.
