Where do you draw the line?

Fiat is terrible, so why don’t you fix it?
Nah, it cannot be fixed, Bitcoin FTW!

Bitcoin still has problems, so why don’t you fix it?
Nah, it cannot be fixed, altcoin FTW!

Altcoin still has some privacy leaks, so why don’t you fix it?
Nah, it cannot be fixed, another newer privacy altcoin FTW!

Newer privacy altcoin still scales poorly, so why don’t you fix it?
Nah, it cannot be fixed, but there’s a research we could build a better currency with!

Research doesn’t use secure cryptography, could we do that with ECC instead so we don’t rely on these assumptions?

ECC isn’t quantum proof, maybe let’s do a new research that withstands a quantum attack!

Even though new research withstands a quantum attack, it can be done more efficiently.

Even tough it can be done more efficiently, there are still numerous improvements we can make, let’s just research post quantum cryptography more.

Oh no, NP=SJW, heureka, breakthrough in mathematics! With this we can redesign the whole system from the bottom up!

So… where do you draw the line?
