1) The blockchain part or "mining" in case of BTC is a special kind of scam. For getting a coin You must invest into electricity and computing power. In return You get VERY little chance to be awarded with a coin. This chance is so small, it is mathematically ridiculous, but in practise. ZERO! Nada, ничто, nichts... What kind of decent money is that, that everyone can apply by spending real money but only few of many millions are actually given by basis of pure luck?
"mining" supposed to be voluntary and the volunteer get rewarded, not for profit. Also, there's mining-pool to ensure you always get something.
2) The coin part of BTC is a monetary fraud. Although people make transactions voluntarely, they are cheated with the very core concept of BTC. While blockchaining may have some usage as a concept as well as cryptocurrency, it does still not mean that BTC is legit.
This statement doesn't make sense, explain it more detail.
a) why is BTC quantity limited with 21 millions? What limits it?
Because Satoshi Nakamoto set it to 21 million and it's coincidence with biggest number of 64-bit floating point number even though there are many other speculation.
But there's no limit and you can change the production/total supply, you just need community approval.
b) what is the point of decentralised money, if its so volatile, that rate would drop 75% in 6 months (or grows by the same)? this is called a hyperinflation.
That's the risk of truly decentralized currency, the exchange price to fiat can be manipulated easily. Also, you already answer the point.
c) why is blockchain technology better in 99,99% of transactions, than regular private/public key technology?
Who claim that?
d) do You really understand, what is private/public key crypto and blockchain in its core, or they just sound cool?
There's plenty of explanation about asymmetric cryptography, so of course most bitcoiner already know about it.
e) if BTC had at more or less decent chance to boom again, why dont all the richest investors in world buy it?
Because investor don't know or don't believe the potential of Bitcoin.
In market btc is the first crypto currency in the world based on this crypto currency is depend on btc so you need to know what is scam and what is real so you should know the proper idea of it based on this you can’t tell like this because I think you have lack of knowledge of btc.
The whole idea is not viable. Think, how are miners going to be paid, after last coin is mined? The job of blockchaining still needs to be done and in increasing quantities only.
Isn't it obvious that miners still get paid by fees in transaction that they included in mined block?
