Exactly. When I bought it, I paid about 3 grand for 5 coins and my basis for this investment was similar to many other early stage investments - it looks highly convex given it's potential. Is it a guaranteed hit? No, but then again nothing in life is certain except death (taxes can be cheated).There are 2 intrinsic values for BTC (but again, not unique among cryptos) that makes it practical for certain people: payment for illegal activities and avoidance of capital controls by governments. As long as these characteristics can be used BTC (and other cryptos) will have values, the question is just how much. And nobody will agree on that, thus the market exists.
