Visa handles an average of 150 million transactions per day. Bitcoin 
currently handles around 350,000 transactions per day. Bitcoin has a 
total of 250 million transaction all time. The bitcoin blockchain is at 
135GB and growing. So if Bitcoin is to reach Visa volume with it's 
current algorithm it will need upwards of 120GB of new storage DAILY!

Bitcoin doesn't scale AT ALL.
