The Dev should consider using some sort of proof of individuality ( like confirming a telephone number ...etc) to distribute some of the coins it will be more efficient method and it will reach out to a lot more people than the cash back program.
Why?
It would be way more beneficial to everyone if airdrops finished for good. That money would be better spent on dev, mkt and other productive stuff, plus people waiting for future airdrops means LESS people actually BUYING.
It is way better if price does x10 due to that actions than if we all double our stash via airdrop but the price stalls (or even dumps right afterwards).
Not knowing how the remaining coins are going to be distributed cause a lot of uncertainty. Investors hate uncertainty.
The entire distribution model was a disaster of cataclysmic proportions and still is.
Rip that band aid off now and just BURN the rest of the coins.
Burn them into the abyss keeping a very small proportion to fund developments and watch the price increase nicely.
Even better fork it and null the known other ico bb wallets and burn those too.
They had a cheek claiming them anyway.
Nobody will even talk about it after a couple of weeks and any icos complaining will look like complaining scabs anyway.
Just do it, i mean we went back on the full moon distributions and pissed off real investors I couldnt care less about upsetting other greedy ICO managers.
That's what i'd suggest from here on.
