user68641: I want to make own coin. I have marketing cooperation team. I am main developer.
[Questions]
1 Making coin with pow and qr-code transaction function is possible for one man developer? Me, know C# well, but not yet C++
2 And currently bitcoin's transaction processing speed is 7 per 1 second, right?
How to increase this? How can it achieved? Is it at least possible? 
Or it is impossible because crypto itself is decentralized? And what is maximum transaction processing speed can be achieved currently?
Thanks.

user51948: I'm afraid this is much too broad, its impossible to say whether you will be capable of creating a coin with your level of programming skill but its unlikely you will be able to if you are asking these questions, which shows a lack of core understanding about how bitcoin & other cryptocurrencies work. Bitcoin is coded in C++ and its testing framework is coded in Python so C# is not directly applicable to that code, but there may be other coins you could fork from and modify, or you could learn C++. But indeed, if you don't understand why the current transaction limit is in place or have not seen any of the research into more efficient transactions then you won't have the required knowledge to make meaningful improvements to how it works sorry
I'd suggest doing a lot more reading of firstly how bitcoin works at a fundamental level including raw transactions, block construction, etc., and then into research of scaling improvements that are being worked on such as lightning, MAST, how segwit works, etc. Note that if you want to help contribute to scaling research in bitcoin, that's a much larger and more useful area than trying to create an independent currency IMO :)
