I'm more concerned with price sustainability than the highest peak reached. During the previous ATH the price peaked at almost $20k at the end of the year, however the average price throughout the year was much lower than that, and the price quickly plummeted after that.
It's because we're already in the bubble that time, so after reaching ATH, the bubble then are burst and next come the bear market.
So far this year we have witnessed increased stability, registering the highest annual average price. If we can have slow organic growth Bitcoin could attain and maintain high peaks, rather than a rinse and repeat profiting.
Of course, there has to be drops after spikes due to speculation and panic sellers (who fear a price drop), but if this correction is not too wide, it would be a huge positive and could lead to more adoption of bitcoin.
We could see some drops, or as others wanted to put it, healthy correction. But I'm not seeing any ATH this year, we may get close, but it the 4 year pattern are going to be used as a gauge for future price, it could be 2021.
