Plenty of individual transactions (at least on this recording time scale) and not a flow as an economy would daily. Plus some odd transactions where money is allocated to several wallets at the same time.

I wish it had the relative size included in the visualization.

This is a real-time visualization so I wouldn't expect anything else even if it was showing USD, it's not like the supermarket immediately turns around and sends my payment to someone else as soon as I grab my grocery bags.

If you just take a 10 min snapshot of transactions in any currency I don't expect to see a lot of transactions flowing to each other.
