Hi bitkilo,
thanks for making research in that important topic and not blindly following the allegedly easy answers that some business men provide.
i am in favour of bigger blocks too and always was (check my post history). but i would never sacrifice bitcoin´s immutability and cencorship resistance because bitcoin would be worthless in the end when we do reckless on chain scalling (= more centralization which you can already see today with the Jihan Wu cabal).
the best way to scale bitcoin to the next level at this point is SegWit. We would already have SegWit since at least 4 months but it is stalled due to political games and powerplay (-> Bitmains Asics Boost Scandal).
SegWit will give us 2 MB blocks + additional features - the best of all is the Lightning Network! LN means instant, secure transactions and is a REAL scaling mechanism. There are multiple teams working on LN right now.
(LN is already in Alpha status and working / ready when we have SegWit.)
please watch:

You can even buy coffee with that

But that is not the end. There is more. You can find additional scaling research on:
