Congratulations on joining Steemit!!
I'm quite interested in your comparison of the fiat market to the crypto market. To date, I have treated it like penny stocks from the dot-com boom. i.e. It's fun, excellent to play with money you can afford to lose, but hopefully make large gains - but I am conservative.
With respect to value ... there are many posts on that. There's one from about a year back by @charlieshrem about the currency in prison. For them, cans of fish were a currency (contains oil, salt and protein - not controlled by the authorities). All currencies are a commodity that someone is willing to trade for. In fiat, that trade used to be gold. Now, few countries back their currency with anything.
If they need more, they simply print more. If they print too much, other money "buyers" will devalue their currency a little. With most cryptocurrencies, the block rate is established from the beginning - so as a consumer, I know how many "coins" will be minted per hour and in most case, I know the total number of coins that will be minted.
This conversation can go on for hours ... As I'm sure you are aware - and is always best accompanied by a nice pint.
Fully agree to that! Will take your comments into consideration. Thanks.
