Good analysis. I have been wondering whether or not it is BETTER to hold DEC in its original form, versus buying "Orb" packs (of which I am now purchasing one "Orb" pack per day) and gradually accumulating legendary and gold "Orb" cards which then boost my DEC income. The DEC is also locked into the value of these "Orb" cards, so even if/when we are no longer able to earn DEC in battles the DEC will ALREADY be "in there". Perhaps I am not accounting for something, but since the "Orb" cards are limited edition I am banking on using my DEC in the immediate term to grab as much of that "Orb goodness" as possible while it lasts. I'd rather have the DEC WORKING for me right now than just laying stagnant n my Steem-Engine account. The bottom line is that a boost of 20% DEC earnings for each "Gold Orb" card used in won battles significantly increases the speed at which you can replenish potions, and try your luck at landing a "Minotaur Warlord (Gold)" card (of which I have now gotten THREE of those FRIGGIN' guys - at $200 USD each), which of course could be liquidated for DEC as well. But I am open to other/better ideas...
