I'm longterm bullish on BTC, so a low price is an opportunity to buy, not a time to beat myself up for timing the market wrong. Of course, I could be wrong in my bullishness. It could all fall apart, or one of the other cryptocoins could prove to be "the one" (though I tend to think most are just also-rans and can and should be ignored). But, I'm absolutely confident a cryptocurrency, of some sort, is absolutely the future. It's one of those unstoppable forces, I think, and as long as the number of people preferring it to USD (or other fiat currencies) keeps rising, the real value (not the exchange value) of BTC is going to keep going up. I want as much of that future as I can afford.
