Basically it all boiled down to which would appreciate better: BK or BTC.
That's no different than any other ICO or altcoin. What is different though, is that BetKing has an actual working product already.
The buyback also prevents BKB to bubble up in price like most altcoins do. You can't pump something that has a fixed price somewhere else.
This is why BKB is really hard to get profit on it, there are people where they want to get profit through this, like buy loe and sell high, most altcoin will be always like that. I do not know why they want to have some fix price here? I know for long investment may be it is really good to have this fix price but this is altcoin what would you expect if there is no pump and dump?
