A minority portion of the premine is being staked to give the dev team a continual source of income that helps pay for both current and future expenses. We would not be able to professionally build and deliver Sigil Go, hire a developer to overhaul the wallet, hire a community manager, make great commercials, and do wonderful press releases without staking. Many incredibly successful projects, like Zcash and Dash, have found that a continual source of income is the secret to reaching a billion+ market cap. We use our staking rewards to further Sigil so that it also stands a chance of joining those ranks.
By minority portion, he means approximately 1.1 million SGL of the 2 million SGL pre mine. The only dev who wasn't staking, left, and the staking issue was one of the reasons for his departure because the dev didn't think it was right to stake the pre mine. But Ty doesn't care. If he did, (and still WANTED to stake) he'd be upfront, bring figures forward (which dev wallets are staking) make an OFFICIAL announcement on staking (timeframe, wallets staking, percentage of all PoS blocks being taken by devs, include in the ANN main page that PoS will be mainly used for dev funding etc...) Ty insists on saying a "minority portion" which is a flat out lie dodges any questions of timeframes, and threatens to ban anyone who criticizes his methods in the Slack. Great job.
