Well, you don't do it everyday, right ? once you sync, you keep it synced - me personally, I sync once a week and it takes a coffee break to sync.
My point is that you can't sync, whether you've synced before or not. It becomes impossible, because you can verify up to 500 transactions per second, whereas the network is growing by more than 600 per sec.
600 tx per second ? you know what's the current maximum for Bitcoin is ? 7.
I know, but I don't claim that it can scale on-chain. I'm big proponent of off-chain solutions because I acknowledge that there is no such a thing as on-chain solution on scalability.
Monero is way more scalable today, there's no argue about it.
Correct, but what matters, IMO, is which one is more scalable over the long term.
