Is trading crypto with gambling the same category? I don't think it's included to be banned. Perhaps Russian regulations have a different point of view and application to crypto. They are concerned about a significant financial shift from banks to crypto.
Even Russia has many crypto projects like the Waves Exchange if I'm not mistaken they dominate in Russia so actively. It is clear that the regulations of the Russian government will be very difficult for them to accept. Even other crypto projects provide great opportunities for Investors to enter. Just because you can't control it, why not provide certain conditions so that it can't be banned.
