Going one step further, premine in any form (ICO, airdrop, bounties, etc) is not acceptable.
If a group needs funding they should use their own money if they're confident (if not then why bother) or get it from the outside, not tied into the project via coins or tokens.
And if they want ongoing funding, they should use the model which automatically transfers a set percentage of each blocks' reward to a dev address.
I have laid out countless reasons why .. all of which are ignored.
Why ?
MONEY.
The thing is people with MORE money make LOTS..
Then the little guys co-op the "coin" for a small slice of profits..
..regardless if the "scheme" is legit.
...
Um, there is no way to stop ICOs from taking place, so this line of thinking gets absolutely nowhere.
There are plenty of legitimate cases in the crypto world that started with ICO's... Ethereum being a case and point. It's a different world since that time though, and the model they used for an ICO is no longer legitimate.
ICO Funds need to self be ESCROWED, and ICO's need to layout their own payout and development plan. If promises aren't kept then people need to be able to withdraw their remaining share from the escrow (can't withdraw what is already spent). The crypto world has the solution to it's own problems in it's own hands... Smart contracts can go a long way towards making ICO's fair and safe.
