I guess most would say they would find ways to reduce transaction fees, increase block sizes to speed up transaction processing...because those are the things that annoy bitcoin users the most. But I believe that the developers also see those problems but there must be a reason and until now they have not intervened or come up with any solution.
Absolutely all we can do is complain. We have no actual ability to solve these problems ourselves. It’s probably difficult to find ways to do what we ask for without compromising other features of bitcoin. Most especially its security. If making a solution so that transactions fees wouldn’t be so high anymore would require for bitcoin’s security and decentralization to be sacrificed then a lot more issues would come up. Just hoping that one day we actually get some good balance between the two issues.
Bitcoin is currently good but I know there are still more to it that needs improvement. And the good thing is, at the end of the day, only us the bitcoin enthusiasts, investors and traders will be the one to benefit it the most.
Even if the developer cannot fix or improve those problems, it is not too serious because nothing is perfect , so we need to accept it and not demand too much from bitcoin .
Although bitcoin has high transaction fees and much slower processing speed than altcoin blockchains, in return it gives us decentralization , privacy and security that no other altcoin has. Just like if we want to use high quality products, we need to spend more money to buy expensive things. Everything has a price to pay, we cannot demand cheap but high quality things. Even we ourselves are not perfect, so we should not be strict or set too high requirements for everything.
. As for the remover, would be wiping out ordinals and anything that relates to it. Tired of experiencing regular high TX fee caused by congestion.
