Every time I think of all the coins I sold worrying about getting ROI on my Titan, it makes me want to cry.  My Titan would kick out 9 coins a day when it first arrived.  Even after the difficulty went higher it put out 6 or 7.  Then post halving 3 or 4.  At these prices, that would be some heavy profits.  Instead I sold out early on worrying about getting my fiat back.  I still have done really well on the Titan and have a decent stash, just think I left a lot on the table.  If I had only believed as much as I claimed I do.  Long story short, I plan to hold this time around.
