Paying for gaz with usdt or usdc for russian gas could be the neutral option instead of using btc becouse putim dont dont have that good exchanger to exchange that large ammount of money to rubles or btc unstable big volatility not option but usdt or usdc has good volatility also you dont need to exvhange this usdt usdc are stable so it could be used very for large transactions.
What do you mean by the neutral option? Do you mean "wise decision"?
First, it is the right of the Russian government to decide whatever the payment tool for their gas or oil. They are the seller, so it depends on them to accept whatever payment tool they want.
Second, I don't see that stable coins are better than BTC. If we look at the security of BTC and stable coins, I assume BTC is safer as it is the number 1 crypto coin. If the Russian government doesn't like its volatility, they can convert it to their currency and not hold a long time. Nothing wrong with BTC and we actually can deal with the volatility.
How do you know Putin has no good exchanger?
Once he decides to use BTC as the payment tool, he must already know well how it works and how to exchange it in a secure way. Putin is a smart person, you don't need to doubt his knowledge or his capability about crypto. And he shouldn't do it himself, don't forget that he is a president.
