8.3: DTube has already brought many people to discover STEEM, and we just want to push this further. The idea of a decentralized video ledger (with proof of work / reward pool) is a clear use case for blockchain and dpos.
We have no idea how much STEEM was purchased from users who discovered STEEM from DTube, it would be very hard to even estimate. But nonetheless, we will keep on bringing many real people on STEEM, some of those have money and will organically purchase steem or try different services/apps in the network.
We are open to suggestions, if you think we can implement simple solutions to our product to increase the average 'investment' of our users, without killing the '100% free to use' aspect.
8.4: We are a struggling start-up with limited funds, it is technically impossible for us to 'purchase' the delegation with cash or equivalent, even though we understand that's what you'd prefer.
However, we will soon have our own token (DTC), with a public tradable value, as well as a similar voting power mechanism as STEEM, that allows generating curation rewards. We would be okay discussing trading either stake for stake, or delegation for delegation with SteemIt Inc. However, we are still in an early-stage ourselves and such a deal can not really be discussed until we launch our own main-net (before the end of the year) and our token gets traded on the markets.
We are also open to helping SteemIt Inc with our accumulated knowledge about the video industry. For example, we could facilitate a video upload feature directly from steemit.com.
