Yes, I received GBB in the last two airdrops, did not sell any shares and am planning to purchase more when I feel the bottom has been reached.
1. Broad distribution - over 98% have been distributed for free and many of the new owners are whales, many of these are whales who have large unrealized profits in BTC that may be invested elsewhere
2. Unique technology - useful for more than just a currency, functionality includes conditional payments, flight delays bot, asset manager bot (custom token creation), etc
3. Free call option - we still don't know what black bytes are oirth, but this sweetens the deal for long term GBB hodlers, we could be pleasantly surprised
