When I combine all tx/s of all the cryptocurrencies I need even more energy.
Also Visa is only just one company, there are also Master, American Express, Paypal, SEPA transactions and a lot more.
So I don't understand what you try to tell me and how screaming improves your argumentation.
combine the tx/s of all the cryptocurrencies out there right now and I assure you it exceeds Visa's 1700 tx/s. NOT ALL TRANSACTIONS HAVE TO HAPPEN ON THE BITCOIN NETWORK! There are thousands of coins!
