Lisk is NOT a pump and dump coin and it is worth fighting right here and right now to keep it that way.
once any coin hits the exchanges it's open season for the market to decide what happens to price. the price is a reflection of all variables, and whales are a well known variable factor in crypto trading.
If after the ICO closes on Monday things look difficult Max and Oliver could have a rethink. It can come under 'force majeure'. indentured servitude is a thing of the past.
I would suggest a full refund and a new ICO, issued by an incorporated entity this time, and with limits on individual contributions to the fund. the rules need to be better thought through imho.
