The sanctions are nothing to them.
They've already made their own rule for the countries that they're dealing with and it's in favor of them. So all of the people that boycotts them or not, they won't care.
You decide if all casinos based on Russia will be boycotted by you or you don't do anything as that doesn't concern you and they're just businesses that are residing there and as well as affected by the war.
I think Putin was prepared for the fact that Russia would be subject to sanctions and he certainly secured himself for at least many months. Even if these sanctions make his life difficult in some way, they will surely not change anything in short time. Putin knows that all countries that buy gas and oil from him will not find new sources even within a few months, so nothing will change for now. However, in the long run, Russia will certainly lose a lot, because what is happening in Ukraine is huge costs for them.
He had already anticipated on what would happen specially these sanctions is already that likely to happen which it did really happen and he already prepared for that because if he's not then he had already stopped
this war early but it seems that he is already prepared and doesnt really bother him at all or simply been ignored considering that they are really rich in terms of economy but as said this wont really sustain
for long term.They might able to hold up for too long as of this moment but that wont surely be that unlimited.
