A benevolent whale could buy up BTS and provide liquidity for market makers. That in itself would be immensely profitable for both the whale and BitShares as a whole. Secondarily they could hire someone who knows about interaction-design/marketing/market-analysis to figure out how we can best create our interface, if we should have one or several interfaces to BitShares, how they should be branded and feel, and how the introduction-process to BitShares can best be accomplished. In addition to this they could hire someone to begin creating a Global Gateway Alliance or something like that to provide resources like documentation and help to entrepreneurs to set up their own (profitable) wallets and gateways in their own jurisdictions for local currencies, precious metals, to interact seamlessly with the global exchange. Finally they could help fund the current developers full time and make sure that they stay voted in to provide code fixes and upgrades, general infrastructure, documentation and support for new developers, as well as new features (bond market, etc.).
Spending even just a few million dollars on this in 2016 I think could easily send BitShares to 100 million marketcap and beyond. An investor buying up $500k worth of BitShares would probably make his money back with a return already by 2017, not even mentioning the earnings from market-making, referrals and gateway transactions fees. They would then also have a foothold within every aspect of the BitShares network that can provide an endless stream of new opportunities if this is a success. BitShares is already in line to get network effect and a small push like that would make it almost certain to dominate the decentralized exchange sector. I think people still do not realize how big a deal this is; a global, decentralized, frictionless tranding network that cannot be taken down is absolutely insane, and we actually have the speed/volume capacity and scalability to pull it off beginning right now. The best part is,
nobody knows yet, nobody knows what BitShares is capable of, there's endless talk about blockchains and bitcoin scalability and ethereum apps, but this chain is live right now, everything ready to
impact the lives of a billion people.
