I feel like bitcoin supporters, in talking about things like the convenience and simplicity of transactions, while not incorrect, are missing the critical issues that are going to determine bitcoin's fate.<p>If we look at bitcoin vs. US banknotes, a paypal balance, a pile of gold bars in a bunker, whatever, if we're looking at how bitcoin performs vs. all these things at the moment in time when we're transferring them to someone else, bitcoin is superior in every case. The problem is this window is brief. Non-transactional moments in the life of bitcoin is where the problem lies.<p>Looking at historic pricing of bitcoin, and seeing a peak at a little over $1k, what does the future price need to be for people to feel comfortable receiving bitcoins and just holding onto and forgetting about them, in the same way they could with, say, 100 bucks in their wallet? Being divisible down to 8 decimal places might rationally address the issue of how to spend something where the base unit costs as much as an Xbox. But even if bitcoin could somehow split at something like 300 or 500:1, to make a bitcoin roughly equal to a US dollar or a Euro, does that really solve the problem of perception? The historical chart, with the accelerated volume and insane swings in both directions, might never recede from the mind of the public.<p>I just have a hard time understanding what a path to acceptance as a legitimate currency looks like. Years of price stability would be a great start. But the beginning of that period hasn't even begun. In the past month alone, the price has moved by 30%, and daily volatility regularly sees the price change by 5%. I can sort of squint my eyes and imagine scenarios where bitcoin, the currency, wins. What I can't see is how bitcoin, the speculative investment, also does well. That these two things are at odds leads to other issues, too, but this is already unnecessarily long.
