Oh, it might look for us as much, but when you take into consideration how many we are in this world and how some spend money it becomes peanuts.
What's the point of clogging up the network for a day? You'll be spending around a million dollars to force people rise their fee rates. So what? And how long can you retain this attack? If it's money waste, then it can't operate forever. There has to be profit for this to realistically occur.
And even one block a day, that's close to 1% of the capacity, imagine the headlines and how much Bitcoiners would laugh if a kid were able to cut 5% of Visa capacity in day with $30k.
Honest question. I know you're a miner. How do you expect for the network to survive if the average transaction fee is not extremely expensive in the future? Comparing Visa with Bitcoin is like comparing apples with spacecrafts.
