We're at 15GB. I think I heard the Ethereum blockchain is at 10GB already. And nobody actually uses it for anything yet. I say good luck to 'em.
The data are a bit rusty for btc (and the numbers for visa are also calculated wrong)... Right now we are closing to 70gb with btc.
You really think miners are complete idiots, then. Chomping at the bit to bloat blocks to infinity with free spam...
~Come with me, reader, into the mind of the economic central planner... where "capitalism" is one broken production quota away from abject devastation and horror.~
If miners didn't mine txs => "Ohhh those bad miners are not mining txs... we must hard fork to show them a lesson"
If miners do mine txs => "Ohhhh those bad miners are mining junk txs... we must give them a lesson"
Whatever they do, it can be used for political friction.
