BTC is measured on the daily, while the nasdaq is measured on the weekly. I think we can compare these timeframes because adoption was much more difficult back then. Also news spread less fast than it does now, so it would actually be unfair to measure adoption and accalleration on the same time frame. However there is going to be an error in the exact measurement anyhow. The ratio of the last move before the last parabolic move is measured with fibonacci extensions to find targets. Possible the first target where a reversal is likely is the 1.61 which is the same as the nasdaq, but because there is more time left when we extrapolate the time span, we could also hit the 2.61.
