Is the service and profitability, even if bitcoin is highly volatile, are the only two reasons why bitcoin is attractive to investors? Any good opinions or answers? Thanks
Because it isn't. Volatile. Zoom out and see the graph, it is steadily going up, slower with the pass of time. If you buy today, wait a few years or so. Then you'll understand.
Short term is useless except for traders. Don't pay attention to the little fluctuations you see from week to week or even months, you have to look at it at years, and perhaps decades.
Bitcoin is valuable because its secure, AND uncontrolled. Its rules are defined in code, not by some politician or banker whim. Which is why its price on the market float freely, its a proof of its freedom. Be wary of altcoins that artificially peg their price to something else, because there is something going on, as with any fiats that have done the same in the past (with dire consequences).
Did you know: The Venezuelan bolivar (VEB) was "pegged" to the USD to around 1 600 Bs in the year 2004? Do you know how many of these would it be today for 1 USD? 2 100 000 000 000 *.
* 1 000 VEB = 1 VEF (2008), 100 000 VEF = 1 VES = (2018).
The current monthly wage for a full time 8/hrs 5~6 day/week job is equivalent to 2 USD.
And some say bitcoin is "volatile", from 0 to 10k in 10 years while the State backed bolivar lost 8 zeroes... And people trust States and banks, because they have never lived hyperinflation or bank runs in their "perfect" run free market economies... America had their little house bubble pop in 2008, yet they didn't had their fiat lose 8 zeroes in the very same time span... Perhaps they would have, if socialists had their way and the State assumed everyone's debt.
Of course, an Austrian economist would oppose bailing out the banks, let them go bankrupt, rather than helping them, which is a form of State intervention out of "fear", which is what made the bubbles form and pop in the first place, the mistaken Chicago school they keep following like dogma, the same that fears deflation and promotes debt...
