I knew that, but I didn't realized it was that long to verify the txs. thx again for your inputs. And why not simply a 10mb block? it wouldn't be that big a difference from now...
10mb would be more than ample for the current state of Bitcoin. That would be capable of verifying about 30 to 40 transactions per second. Maybe less since more empty blocks would still end up being mined. However, if Bitcoin wants to compete with the big boys and feasibly be used to buy a cup of coffee; gets the mass adoption us HODLs crave; then we need to find a way to verify thousands of transactions a second. I only see an off chain solution to get us to that step.
