Hi everyone. I understand the idea of blocking Visa/MasterCard in Russia for destroying economy and hurting Putin, and I kinda agree with it. The only problem — this sanction will also lock a lot of IT-people inside Russia, which is provide another chance for Russian economy (due to this people have upper median salary in Russia and they have massive influence on local market). Also this sanction will slow down the "brain leaking" from Russia, which is also can influence on stability of Putin regime.
