I am glad people are starting to ask theese questions. This is where Bitcoin Cash comes in. It is methodically designed to scale to world level usage, just as Bitcoin was supposed to do. It can already handle 10 million transactions per day and tests have been done up to 1GB blocks on micro hardware. (https://read.cash/@mtrycz/how-my-rpi4-handles-mining-1gb-blocks-e5d09d83)
BCH has also done away with blocksize limits and implemented an adaptive algorithm (ABLA) to match blockspace with infrastructure, TX volume, and other dynamics. There is also work going on regarding miner validated UTXO commitments which would allow for decentralization and security while keeping only a small percentage of the chain.
Can Bitcoin Cash scale technically to global reserve currency?
Yes I do that as well, but this was a real atomic DEX which supported hundreds of coins. They decided to bend the knee to try and attracts “large professional liquidity”. When will people learn going KYC defeats 90% of the purpose of cryptocurrency?
