Wow, quite a rise. Well done. Proud to have (+1-1=0) against you, even though it was not blitz, but a much more unpredictable bullet. 
2100+ Blitz
Amazing progress!
Maybe you're the new Nakamura (who famously rose to the top employing pretty much the same method as you are doing).
Your study and quick absorption of opening system is remarkable and reminds one of the way masters play and think. You blend it in with strategical understanding and good tactical vision - so there's really no reason why your rating shouldn't keep rising.
Messed up move order, gave up rook for very little, and made my opponent outthink himself, making him give his advantage back, and then I win.





One of my most important goals has been reached. My next goal is 2200. When I reach 2200, do I expect my FIDE rating to be 2200+ aswell, meaning that I should get the title CM. As you learn a lot of ideas in your blitz games.
My lowest rating was just around 1030. And that was around October 2013, (which was my strength) and after that I started studying chess a little more seriously, meaning chess mentor and tactics, aswell as watching chess videos. Now in a years time, from 2014 I have improved from ~1500 to 2100 (+600) which is quite some improvement, and never have I ever used a chess book, neither have I had a coach.
Here are a game where I played the Reti and my opponent replied with a system that I just implemented against 1. d4 d6 2. c4 e5! 3. Nf3 e4! and then 4..f5 (for black)
Which ofcourse I had to play against him. However, later in the game I blundered and won on time. But the opening is what matters, because that is the main thing you can learn from blitz chess.
