Yes, that would be horrible judgment. Take a note from people who have been making money in other, comparable investments models since investing was a thing - diversify. That doesn't mean you can't have a substantial amount in crypto/bitcoin, but to put all of your money in ANY single thing is just a bad strategy. We can't entirely use past results to count on future outcomes, that's why people got screwed in the dotcom bubble, in the housing bubble, in the tulip mania bubble for crying out loud. I personally have substantial crypto holdings and think that there is a great amount of additional profits to be realized, but you should always hedge your bets.
