It is, but remember no other coin has Bitcoin traffic, though Ethereum might be close. And as far as BCH 8mb blocks goes, if the blocks were always full, it would cost you several terabytes of network bandwidth per month to run a full node not to mention huge storage requirements as well as increased computational requirements as bigger blocks requires more CPU to be verified. In other words, running the full node would be prohibitively expensive for a regular user. This is a security issue for regular users as running a full node is always more secure than using light wallets and SPV (with SPV you have to trust the server you're connecting to some degree) as it is a security issue for entire network as smaller the number of full nodes is the less decentralized network. Also, it's worth pointing out that system that gets too demanding to run under the full load doesn't scale well. So block size increase does not solve scalability issue.
That might be true, but there are other people, myself included, who cares much more about stuff such as decentralization or technological innovation than they care about investment profits. And from both of these points of view, BCH is trash. Also, there are other coins, that might have better ROI in medium time frame than BCH.
