One dev? That is a good one. I know many good developers and I know the limits one dev can do. Even if one is working 24/7 it would not be possible to do such progress in so short time. I would make sure to check progress Energi made in past two years before posting such a statement. If Andrey is that special to code all from day one till today why is he bothering and wasting energy here to attack another project? He could start his own. He can easily code something amazing in a few months and make billions with his own project. But again, he doesn't really believe in cryptocurrencies as he stated.
