I'm not so sure about that. You could have bought BTC anytime before the past week or so and it would have appreciated significantly, regardless of whether you bought it in a peak or trough. It's just a question of magnitude. E.g. if you bought 1 BTC at the lowest or highest price in 2015 you would still have outrageous returns on it today.
This is not to say it will continue being the case going forward but it's crazy to look back at.
