Who made money during the $100 --> $1200 BTC spike, it was too easy which makes me think exchanges robbed people that listened and invested at $100 to get a return of at the least over $500. I was a victim of this selective scamming by BTC-E. How many people do you think made millions in profits off the BTC bubble?
Bitcoin isn't an investment, it's a currency.
Bitcoin isn't a currency. It's a protocol.
You're confusing the blockchain with bitcoins. Bitcoins, millibits, microbits, and satoshis are currency units.
How can someone confuse blockchain with bitcoin?
What you said doesn't even make sense. 
Bitcoin is a protocol. One of its applications has the characteristics of a currency. You welcome.
That's a good question and one that you'll have to answer. There's no way I can do that for you. If you reread the original post it's very clear that the OP is referring to a currency, not a protocol. According to your logic, the blockchain will never have more than 21 million protocols?
