USDRUB worst case scenario

if you haven`t read my first article when i expected the 86 level to be reached after the Russian ruble was no longer aligned to Crude Oil price:
or the 95 target after the Ukraine invasion:

this time i expect, considering all the sanctions and the fact that exchanges are selling USD in Russia for a price at least 30% higher than the forex market; i even saw a picture where 1 usd was selling for 250 RUB, then my prediction in 150 this time, or the dollar to be 2X stronger than it was at the beginning of this was.

Looking forward to read your opinion about it.
is it true that the US Dollar is already trading so high at the exchanges?
Is Bitcoin a safe haven in these times of uncertainty?
