@Dooglus an interesting note:
Taking the payout line that was used:
[ 121, 47, 13, 5, 3, 1.4, 1, 0.5, 0.3, 0.5, 1, 1.4, 3, 5, 13, 47, 121 ]
We naively assumed the house had a 1% edge, but actually it's an illusion.
We can actually normalize this payout line to:
[ 172.42857142857144, 66.71428571428572, 18.142857142857142, 6.714285714285714, 3.857142857142857, 1.5714285714285712, 1, 0.2857142857142857, 0, 0.2857142857142857, 1, 1.5714285714285712, 3.857142857142857,66.714285714285714, 18.142857142857142, 66.71428571428572, 172.42857142857144 ]
So when betting 0.7 BTC, it's an identical bet! The EV stays the same (-0.01 BTC or what ever), but now we calculate the house edge, we'll figure it out as 0.01 / 0.7 ... or 40% higher.
The "super payout" line you had, just exacerbates the problem. The most you could lose was ~4% of your bet, so with a 1% house edge, the *real* house edge, after you normalize the payouts would be 25%!
So while crazy, it's not as crazy as you'd first think!

One take away for plinko players would be that the house edge is rather misleading. You actually pay the house edge on the entire bet, rather than just what you're risking.
