if you don't invest you have one chance to gain usd from a rising BTC and one chance to loose from a falling BTC but if you had invested you have to chances of loosing usd one from the falling value of investment and one from the falling price of usd (if BTC rise in value you would be better not to invest anyway). I really hope you understand now what I say and don't twist my words so you can be right about this.
Given this logic, you also have 2 ways to gain. You cannot say you have two ways to lose, and then ignore that you have 2 ways to gain. I'm OK with using whatever logic you want, but the end result is the same. Purchasing power is what matters when dealing with multiple currencies. I'm simply stating that you cannot currently measure purchasing power over time in BTC. Can we agree on that, or are you aware of some website that prices goods competitively only in BTC and does not adjust them per the exchange rate? Spoiler alert, one doesn't exist.
It is not me who doesn't understand. I have decades of trading experience with multiple currencies. I would have been fired had I made an investment in Zimbabwe and then tried to justify it by saying that I was seeing huge annual gains in Zimbabwe dollars. That is in essence what you are all doing with the line of thinking in this thread. I really hope you understand now.
There is a reason why all major companies that you all get excited about when they start accepting Bitcoin use USD to establish their pricing and not BTC. The securities (I use this term very loosely) exchanges don't price in USD for legal reasons, and that tricks the weak minded into not seeing what is going on. Hence how so many people without global trading experience come here and complain about all BTC securities. They simply don't understand what they're doing and try to blame the market instead of themselves.
You didn't had two ways of gaining. We talk here about facts that happend, not in theory. In theory of course you also have two ways of gaining if you invest in the right securiti. The point is this: until now that didn't exist (except for Asicminer). Let's both face it: investing in btc securities was a bad ideea, and we talk here about buying at the IPO and holding, because I admit there are people that made good money trading those securities.
Please understand this is not a fight and not about who is right and who is wrong. It's just the fact that until now bitcoin securities had only brought big loses to investors.
