What do we think that is the technical way to get rid of congestion in bitcoin network, what method can be apply to shortcut transaction congestion of bitcoin,
Developers are constantly trying to improve bitcoin but we already have a few protocols that have been implemented to try and reduce transaction fees. One is Segwit where it basically changes the format to reduce the size of each transaction so that more can fit into a block. Layer 2 or Lightning network solutions have also been implemented.
and what makes Bitcoin and ethereum always have higher congestion more than any other cryptocurrencies, the question is that why the demands of bitcoin is always higher than others?
Simply because it is the first cryptocurrency to have been made. It has set the standard and the rest are seen as just imitation of what the original is which is bitcoin. People are most likely to think that the original one is the most credible and legit compared to the rest that follows especially that there is now too much coins/tokens out there
