ABC doesn't look like it's getting bigger blocks anytime soon. Also the REASON for bigger blocks is very important. SV wants millions/day more txns on chain as soon as possible.
Codebase is the same. Limit is 500x over the demand. Certainly enough until next year. About millions tx/day, from where, who do you think is so eager to use the blockchain?
Remember that you're using the future uncensorable twitter? There's a few tens of millions+ of txns/day more. Need I go on? How do you expect miners to pay their bills with no volume?
My buddy works for a medical robot company that wants to use a blockchain for secure diagnostic sharing globally, the fastest/cheapest way will of course be op_return txns on SV.
Fincen companies need secure ledgers, right now that mission critical infrastructure is very expensive to maintain. SV can do it 2 orders of magnitude cheaper.
There's a guy here in Tokyo who is putting all land registries on the planet into the blockchain and using a searchable database that's quicker and easier than any government's.
