I feel that if they accept cryptocurrency as a technology, then all these forks will simply disappear. And there will be one global currency, which will be the most ideal market option for all.
Agree. There are so many useless forks and altcoins nowadays, which serve no real purpose other than speculation. If the mainstream world accepts cryptocurrency as a tech for real purposes in life (instead of as an investment tool or speculation), then Bitcoin would've become a more serious cryptocurrency that would dominate them all. However, so many forks out of the Bitcoin blockchain, would destroy its credibility, IMO, since people would be afraid of investing into it in the first place, with fear that their coins would get double spent in a split.
Not implementing replay protection (like Bitcoin SV did) could be extremely harmful for the underlying blockchain that has undergone the process of a hard fork. Both Bitcoin Cash (ABC) and Bitcoin SV, have had some serious issues during the weeks of the Hash War. If everything would've gone smoothly in the first place, then the market wouldn't had been negatively impacted like it is right now.
In the end, I believe that both Bitcoin Cash (ABC) and Bitcoin SV will die as they don't serve real purpose in life other than speculation. The original Bitcoin (BTC), with SegWit and LN, is heading into the right direction towards scaling in the safest way possible. Huge blocksizes would eventually fail, since people would not be able to meet the storage and bandwidth demands required to run a full node. Hence, only corporations would be able to support the BCH and BSV blockchains if they continue to increase their blocksizes at a fast pace over the long term.
Nonetheless, if it wasn't for Bitcoin's success, none of these forks would've had some attention in the mainstream world. They only carry the Bitcoin name/brand, but nothing more. Just my opinion
