Vijay notes it on Medium too.
I know its on medium I read it and that's why I shared my POV on it, I don't plan to buy his book, but first search if I could get it from someone for free. As many people love to read books and then share them hehe. Overall, to support the writer we should buy his/her books, and I will also consider this option as well, only if the book convinces me too. So before making my mind, I will follow him and read his other readings as well. Overall the topic is not about buying his books etc. the point was to make sure what's the real deal behind BTC.
There are many characteristics make Bitcoin is unique and scarcity is one of them. Scam developers can create their Proof of Work coins with total supplies like 11.5M or 5.525M or whatever smaller total supply number but I believe their altcoins will not have good utility and value like Bitcoin has.
Developers are making such coins and I think we should not call them scam, as they are not trying to develop a coin of the name BTC to scam people, they are developing there own coin (along with Blockchain) or there own token so nothing bad in it until they don't try to scam people by rug pulling or other types. The point is, scarcity is really a big factor, and the only factor that helps it to increase in value is its adoption, and why would people go after 11.5 M or 5.5 M alts while they know this is in the market for long period of time and have more usecases (ETFs approve now as well).
