Very rarely has bitcoin price gone below the 200 WMA and when it did it has recovered after a month or two. Not sure why $30,000 seemed to be checkpoint that took some time to go through other than it is a round number and maybe people had positions at that mark. Anyhow I see no reason why it cannot fall to the current 200 wma ($13,800?) after maybe slowing at $20,000 for the same reason as $30,000.
30k Is a support because of:
1- 01.2021 correction bottom
2- BTC @30k is exactly testing 2017 ATH if we adjust price USD money supply change in 2017-2021 - Just heard about it from BenjaminCowen
3- Hate to say that but - Elon buy zone
Currently, BTC is a great short term buy (32-40k recovery) moderate mid term buy (risk of falling to 20k and beginning of 1-3 years of bear market), great long term buy (after 10 years people will laugh from 30k sellers)
