I think there would be a correction, but it would likely be a minor one. I also agree that the seasonal cycles of pumps and dumps, would soon give way to a more matured and less volatile market; so rather than having a period of pump followed by a long retraction which lasts long with the market losing 50%+ of its value, we would experience a more balanced market with less volatility, a minor correction (<30%) would still most probably occur between spikes.
We can anticipate bitcoin to confront correction at $20k, however it should be less than or max at 30%, it would be $14k at the lowest support level. Nevertheless, $20k isn't the limit for bitcoin in this year moreover in 2021, according to many predictions and technical analysis, bitcoin could be able to reach at least $50k in the next year, so prepared for some corrections but don't sell all of it.
