BTC will very likely be in sideways range whole next year, because we should be currently in 4th wave, which are often sideways consolidations/triangles. In this period, I think we will see true altseason, like back in 2017, there have been +3 years accumulation on many altcoins and those accumulation should resume in huge uptrends.
So despite I think buying almost any "decent" altcoin is much better then buying bitcoin for next 2 years, I think we won´t see that much cheaper bitcoin in next years, so buying bitcoin right now isn´t also bad idea. All sentiment indicators are suggesting, that market is in FEAR mode and buying anything during fear and panic is one of the best long term strategies.
