Oh this is rich. How about a short reading comprehension test.

The writer most likely:
a) Knows many mathematicians.
b) Is a mathematician himself.
c) None of the above.

So you are pretty sure I don't know many mathematicians but can't tell if I am "another scammer"? I will give you a hint. I don't really care if you are for or against cryptocurrencies I just hoped you had an educated/logical reason why. That way this discussion could have some merit. I think it is clear at this point that will not happen.

If you really want to "fight" against cryptocurrencies talk about centralization concerns or even the guy talking about the Bitcoin mafia has a better argument. This stuff about the intrinsic value of "interesting" numbers has no meaning here unless you have yet to make a point. A bank account number, credit card number, and bitcoin address all have zero intrinsic value regardless of how interesting the numbers may be or the non intrinsic value they represent.

Perhaps look up the difference between fiat currency and commodity money and maybe read the white paper. You should definitely not invest in cryptocurrencies you clearly don't know enough to avoid being scammed.

The fact that there are many ways to con suckers is NOT any sort of fault of cryptocurrency.

I must say I find this interesting. A mathematician against crypto. I have to admit, in my ignorance I had assumed the opposite would be true.

On the subject of books I would recommend: Narrative Economics: How Stories Go Viral and Drive Major Economic Events . I would propose that the "success" that Bitcoin has seen thus far has more to do with a narrative that resonates with people than it has to do with the protocols and such. Of course I wouldn't rule out greed as another major factor but the point being it has more to do with people than anything else.
Actually the math involved isn't that complicated (At least for Bitcoin I haven't really looked at the others). Is that what has you upset, you think the math is too simple to warrant its valuation? You haven't yet pointed out a problem. I know there are problems just none yet of much significance. If you know of a significant problem I would be interested to hear it.

By the way, scammers need fools to make money not cryptocurrencies. If you lost money to a cryptocurrency it's not because it was a cryptocurrency

I think you made a slight error in your "proof". You seem to imply there is a parallel between an empty set of uninteresting numbers and an empty set of intrinsically valuable cryptocurrencies. However, following your logic you would have an empty set of intrinsically "unvaluable" cryptocurrencies. It also doesn't matter how you define "intrinsic". At some level cryptocurrencies are represented by something, be it electrons or whatever, which will have intrinsic value. "Repeat ad infinitum and you know the set is empty".

But seriously, you might take a moment to consider you may be too polarized on this subject to the point where it is blinding you to the truth... No one really knows. Personally I wouldn't recommend anyone heavily invest in cryptocurrencies because it is an unknown. If you had something intelligent to say I would listen but you are saying crypto will go to zero after ten years because you don't like it.

Actually I would "trust" any cryptocurrency more than I would you. You could be giving me something nice looking but worthless. Crypto I could validate on the spot. Sure for a bottle of vodka the risk is fine. But for anything of real value representing significant financial risk validating the value of your pretty rocks becomes a lot more of a hassle than most any cryptocurrency.
