Produce a POW coin with fair launch protocol and then token swap on exchange later.
POW is not suitable for the average user and will give advantage to the guys with big mining rigs. And the power costs in my country is magnitudes higher than in a lot of other countries (which prevented me to have a mining rig in the first place).
IMHO there is no 'fair distribution', I hope we can just achieve a wide distribution, that would already be a success.
Anyone can hire hash power and this would be a very short mining period. The only variable is really cost of electricity.
Miners will be taking a risk for the BB
Miners will be investing in it for real
Miners will stop BTC whales becoming BB whales with no risk to their BTC
Miner will stop other ICO owners using BB to crush the BB price to fund their own project
MIners will stop exchange owners being whales to manipulate the markets pumping and dumping on innocent investors.
Miners will stop ALT coin dilution in general.
The alternatives are the inverse of what miners will prevent.
Mining farms will have no advantage at all over anyone else except in the form perhaps of electricity savings and a small factor of buying their hardware over leasing. That was anyones choice to start with. They are not taking the whales share with no investment or risk.
If you are going to do an airdrop this is not the way. This is the worst way to conduct an air drop possible for this coin and all alts.
