The sanction which was imposed on them forced them to discover the beauty of bitcoin, if their was nothing like them having issue with international transfer system their could have been no time which they will highly get involve with bitcoin, but because they needed something which have no limit and boundaries in terms of making their transaction and they don’t need to be control by anyone they have to use something fully decentralized as bitcoin, this is also part of the reason why bitcoin was invented (transacting without limit).
