Bitcoin can scale perfectly fine with big enough blocks. On a data centre connection, you can sync the entire chain in 10minutes. Bitcoin cash can scale to be a world currency with out issue. People are slowly starting to realise that Blockstream intentionally broke BTC with 1MB blocks to give crypto a bad name and try and make people think that they cannot scale and be used globally. This is still going to happen and the people still have a chance to buy some BCH at a reasonably low price. There are probably better coins than even BCH, but it has the infrastructural and all the mining rigs etc already out there, everything that runs on BTC and much much more can use BCH network instead. With SPV wallets and most businesses running full nodes for 0conf transactions, we can move to a totally decentralised peer to peer cash system that cannot be manipulated and governed by central banks.
