I think all the plans to modify supply or slow down emissions artificially will ultimately harm the economy more then help… I believe focusing on demand is our best approach…
Put crafting/ upgrades on a Multi-coin bonding curve would incentive crafting today, as each additional item/installation is crafted and upgraded the price increases… additionally items could be sold back to the curve(burned), for an amount less then it cost to craft.
The bazaar would also functions as a type of arbitrage. Early crafters could potentially sell on the bazaar for a profit, and potentially at a price lower then it would cost to craft.
