I'm such a person. I've been active with BTC, I've mined and traded (both to a nice personal profit), but I think BTC is a loser. I invested in BTC the same way I invested in one-hit wonders like Zynga: very temporarily.

Perhaps we can ask each other some questions:

My first question: BTC is designed with very limited bandwidth for transactions (right now it can only do 7 transactions per second). Is there an actual solution in place to deal with this? All I ever see is hand-waving about how the limits could be raised or eliminated, though that appears that it would create a problem with block chain size and bandwidth.

Is there a proposal someplace that actually addresses BTC's current lack of capacity that doesn't just create a rather massive bandwidth and storage problem?
