MAh, I don't think split it into smaller units will help it.
No not when it comes to moving the decimal place but they need to split the block-chain up
and move towards using a block-matrix because this is the reason Bitcoin will not scale
plus they knew this nine years ago.
Forget Lightning, it's a sticking plaster that uses mini-banks called hubs and if block-chain is so good
like they keep saying then lets keep it all on block with maybe a minimum value that can be sent as
something like $0.10 to stop spam.
Ripple says you can send real small amounts but it would not work for me when i tried to send
$0.50 to a test wallet but it worked fine with $1.00 so they need calling out on this deception
