Does anybody knows if there're short term plan by the official BTC developer team on how are they going to tackle the congested blockchain in the meantime?
Make segwit easier to use by implementing it in the core GUI. We haven't felt its effects very much yet because nobody actually uses it. Once that changes, then we'll start having 1.4 MB blocks.
That's exactly what 'big-blockers' were telling you from the very beginning. SW is too complicated, too slow in impl & deploy ( opt-in!) adoption and still is no sufficient scaling with that little capacy increase and we also pointed out that new 2nd layer tech is not ready, has no 8 year slow start working success story as on-chain has and is too risky to play with a fin tech application in the middle of a sigmoidal mass adoption process.
The ship has sailed now and we have two relevant bitcoin approaches and only one that runs as open (source, discussible, tech, ideas, economy ) as possible.
