New paper on
#Bitcoin
with my collaborator

"Three variations of Heads or Tails game for Bitcoin"
We simplify the computation of optimal thresholds on hashrate for Selfish Mining attacks. We don't need a MDP solver.

I didn't want to comment on Taleb's paper because of the friendship I have with him (that I don't know if it is reciprocal).
But I must honor truth and point out a couple of fatal flaws in his argument that the
#bitcoin
price must be 0.
Below his technical supplement.

Each time
@nntaleb

Conclusion: Not only the absorbent barrier assumption is false, but the proof after that is flawed.
I am told that he is claiming that his paper is accepted for publication. I would be curious to see the referee reports and the name of the editor that accepted the paper.

He is furious like a 5 year old because he couldn't shut me up and because I exposed his mathematical fraud.
Years ago, Paul Malliavin, who was my professor and one of the best XX century mathematicians, accused Taleb publically of being a fraud. The old wise man was so right.

The only response to my objections we got from

His paper is full of errors. I am going to concentrate in only one, with minimal mathematics, so that everyone can see he is a crank.

The mistake
@nntaleb
is making is to think that I am a pussy academic as the ones he is used to insult in twitter.

(because at 1 cent I, and many others, will buy the 21 million coins). So there is no absorbing barrier indeed.

It is indeed quite obvious. The expected prize of a limited asset with some minimal demand, when measured with respect to an infinite inflationary currency, tends to infinite. For example, the expected price of gold in the long run is infinite measured in USD. Same for
#bitcoin
.

(2) More importantly, he overlooks that the expected price E[P_t] of
#bitcoin
can go to infinite as t->+∞. And this is exactly what happens in the hyperbitcoinization scenario!

At the end of the first column, he pretends to prove that E[P_{t+n}|t+n<τ] proving that the Prob{t+n<τ}->0. This does not hold if the random variables (P_{t+n})_n are not uniformly integrable. And they are not for the same reason as before!

Therefore, the surrounded part of formula (2), and in particular the claim "Small as n->+∞" is unfounded.
