Ultimately this will come down to what value Bitcoin really has to society. An investment is when you work to receive something you don't want, but that you think other people will want in the future so that you can exchange it for things you do want. If you work for money then you do investment. By working for money you are betting that when you need food at the end of the week the shopkeeper will take your money. Investing in other things is no different. You make a bet that people in the future will want to trade the thing you buy for things that you want at that point. For example, you could buy a small amount of gold every month and when you are ready to retire buy an annuity with the gold. That's if anyone actually wants the gold in 30 year's time. If they don't then you'll have to eat the gold. People often say that cash is a bad investment, but actually it's really great as long as you plan to spend it soon. What they mean is it's not a good long term investment, of course. But cash stays valuable because unlike other things you can exchange it for things you want almost immediately. Bitcoin is now not like cash because of the high transaction fees. So it now competes with things like gold. So you have to ask yourself: what do you think will still be valuable in 10, 20, 30 years time? Gold? Bitcoin? If Bitcoin isn't a yes for enough people, then it's a bubble.
