> Well, let's not forget that BTC has gone up from $300 to $15,000
Depending on how one measures. Prior to Gox's implosion, BTC was $1,000, which is the price people were actually depositing at. Meanwhile, the fact that we're denominating in USD means that we have to account for inflation if we want to compare historical data, which means the current price is more like $13,000 in 2014. There's quite the difference between 13x and 50x.
I prefer to use the trustee's watermark which reflects the value of Bitcoin after the price manipulation of fake Bitcoin being sold by MtGox had been taken out of the market at $460. But your point is made even stronger if you consider that same money could have been safely invested with a steady interest of 2-4%. And that's if you disregard that the sort of risky investments that that sort of play money could have gone to, nearly all of those investments have been extremely lucrative the past 8 years.
