I think the simple concept of a pyramid system is over your head.
If I mine a bitcoin today, no one who mined before me makes anything from it.
Unless you have a different definition than the rest of us?
I'm talking about the "Reward system" being pyramid based. As in 8 months it will be 25BTC instead of 50BTC. If you join in 8 months time and begin mining you've just immediately halved your Bitcoin mining potential for no other reason than "it's a pyramid reward system, get in early".
Bitcoin is marketed as finite and a deflationary currency, but the reality is that mechanism is in there purely to get people interested and investing in it because they think one day each Bitcoin will be worth ONE MILLION DOLLARS!! Satoshi developed it like this so people would be interested, he licensed it under MIT so people could change it freely (SolidCoin) and then dropped off the planet because the reality is Bitcoin is more the "rocket booster" needed to get the real delivery system (something like SolidCoin) into general use to remove the stranglehold governments have over us.
Read an article about Bitcoin like this, and compare it to SolidCoin. We've fixed the criticisms.
http://www.good.is/post/why-bitcoin-is-a-scam/The truth is Bitcoin will never be an internet currency. It doesn't have enough units (2 quadrillion) to even cover the existing financial system we have, let alone what it will grow into. SolidCoin can grow into it, and it has many automatic ways to ensure relatively stable price that people want in a currency.
