Make it 1:1 then a fair deal
Example:
People spend $1000 in ICO at 1$ to get 1000 Token/Coins
People go now to Coinexchange to spent $1000 and get 33333 Coins
Now These People can swap those 33333 1:1 to new coin. This is fair to you?
Example:
People spend $1000 in ICO at 1$ and get 1000 Token/Coins.
People went to Coinexchange and spent these 1000 Tokens to receive 6000 Dollars.
Now these people who spent them receive new tokens worth $1000 Dollars PLUS they have 6000 Dollars in their pocket because they sold their BTBc.
Is this fair to you?
If you consider it unfair, go to Coinexchange now, buy a shitload of BTBc and be one of those who take the risk that these BTBc remain worthless. This is the price of the game. HIGH RISK, HIGH REWARD. You seem to be a LOW RISK guy, so you deserve LOW REWARD.
