I believe that if the bitcoin stabilize lest say in $2500 it will be seen as more trustworthy and the governments will surely start accepting it because they don't like the instability or the speculation.
Seriously? Going by your logic, why didn't governments consider Bitcoin to be "trustworthy" when it maintained its position above $6000 for such a long period of time? Bitcoin was so stable, that the degree of volatility reached near all time lows. People were even in the process of referring to Bitcoin as a stablecoin. Great time it was to use it as money.
Bitcoin really looked like a stable crypto currency from March to November 2018. In my opinion, the large BTC holders realized that the US SEC would not approve a Bitcoin ETF in the foreseeable future due to the reasons they published in their report. Therefore investors have decided to lower the BTC price so as not to feed the Bitcoin miners.
I believe that the current crash of crypto exchange markets was ignited by forking Bitcoin Cash and creating Bitcoin SV. Although it was probably just a pretext for selling a huge amount of coins and tokens.
$2000 is too pessimistic prediction for Bitcoin price.
