In Russia, lives a large number of excellent programmers who are ready to work day and night. Therefore, if you find an ICO with a good Russian team, you can be 70% sure of its success.
In Russia there is many smart people, programmers, economists, engineers, and to not make this longer important is that Russia proved it self in history so there is no need to start to doubt in them now.
