Seriously people, we need a viable reason for the price to be increasing other than "because it is".
You profess to have learned from the past bubble, but it's clear that people have learned very little.
For example, bitcoin is not a perfect system, it couldn't cope with anything like the transaction volume of even a small stock exchange, hell it'd struggle with 1% of that amount. People were even complaining recently about network issues from satoshidice, when we were running a mere 50,000 transactions per day. That's
nothing in finance.
So, bitcoin's market cap currently exceeds $100m. Is it worth it? Possibly. It's certainly more worth it than it was last year, but even so we need to keep some sort of perspective on what a highly speculative and potentially flawed digital currency is "worth", rather than running off into fantasy land and pretending we're not the ones at fault the next time there's a crash.
People on here have such tragically short memories - only last October everyone was totally sure the price was going to $1. I bought a bunch at $2.10-2.75 just because, despite it being relatively high risk, I believed that bitcoin had value much greater than the $20m or so it was valued at at the time. Nobody wanted to lend BTC in quantity on the forums then either, now everybody's doing it.
Please people, let us not repeat this retarded cycle of dot-com-era style insane valuations and "what could possibly go wrong?" buying, followed by crisis, followed by "It's all over!" selling. We've been here once before.
Rapid price expansion isn't even good for bitcoin. The time of greatest expansion and actual trade in bitcoin was in the 3-month or so window that various people held the price between $4.90 and $5.10. Merchants need stability. If you want to build an actual currency here, stop acting like get-rich-quick naive forex traders and start thinking of what you can buy in bitcoin (asides dollars) that would require you to buy as many as you have.
Because protip: If you can't think of something sensible you'd buy with all the coins you've amassed, chances are the economy doesn't support the price you paid for them
Anyway, I know nobody's going to listen to me, so WOO! $50 by October!
