Same as BTC or BCH or BSV. The advantage over BTC and the BTC derivatives would be that literally ANYONE can earn it, by posting valuable content and being rewarded for it; rather than all the new tokens going to miners who have to invest in expensive equipment to participate in the token's inflation.

BTC investors don't care about the fact that miners earn the inflation tokens. And if Satoshi had 'required' BTC holders actively participate in mining (rather than separating the 'investment' function from the 'mining' function), very few "investor" types would have ever jumped on board, imho.

Also, the advantage over those is 3-second block validation (vs. 10-minute) coupled with zero transaction fees.

A HUGE advantage of proof-of-brain distribution is that it is open to the masses. Another huge advantage is that, because it is open to the masses, it naturally leads to mass adoption -- the network effect is what will ultimately allow HIVE or one of the tokens on the Hive blockchain to overtake BTC and the BTC derivatives (in terms of adoption and usage, not necessarily in terms of market cap).

BTC is being pumped by institutional investors. HIVE (or the alternative I am proposing) will predominantly be 'pumped' by everyday people. The alternative I am proposing allows for both/and -- investors PLUS everyday people.
