You know no such thing: I was, and remain, quite sure of myself, something your strange views of both assessing investments and epistemology in general seem unlikely to shake. Rather, I didn't take your bet because it bore no relation to anything I had said (which you still seem not to have quite grasped).
As for your triumphalism here, it's terribly misplaced, and reflects those views I've just referred to. Compare a gambler who considers selling all his worldly possessions, and then betting the proceeds on black. Suppose he's warned that to do so would not be a smart choice, but does so anyway. Does the fact that the gambler goes on to win make his prior choice a smart one? Of course not: he simply got lucky. Likewise, if he took our advice, and refused to gamble his money, and then black turned out to win after all, it would be puzzling indeed if he started crowing "Do you still think it would have been a bad choice?". Of course it would have!
You are free to sell out of all your positions, and gamble those proceeds on what you speculate (for you've done little more) the price of Bitcoin will be next month, or next week. But that will remain a profoundly silly thing to do, and the fact that you don't do it suggests that perhaps you don't disagree after all.
