Both Ripple and ETH will take out Bitcoin and if you study up on "Lightning Network to the aid" then you
will discover that it uses hubs, they charge fees and are in fact "Banks" so that's more pain on top of
the $25 plus Tx fees we already have today.
See
https://www.youtube.com/watch?v=UYHFrf5ci_gI own and like both Ripple and ETH but ETH will need a major re-write to survive because
just like BTC it uses Block-Chain and therefore will not scale and i have already covered the
Lightning sticking plaster.
Block-Matrix will work and scale and will break transaction processing (Not mining as they call it) down
between nodes which involve some centralization just like Lightning needed anyway for it's hub/banks
ETH developers are pro active, BTC developers are sitting on there hands and cannot even come up
with a temporary fix on Bitcoin to limit the fees and have been taken over by greed and big finance.
I can see Ripple becoming a conduit to get money from XYZ coins back into fiat at the bank
and have no love for bankers but unless we get our act sorted out and that's not going to be
$25 in fees from a white paper that said
"Virtually free transaction fees" and on a public
ledger then Ripple will take over.
Mining coins and PoW is the biggest pile of crap ever invented by someone calling themselves
a programmer and the king has no clothes on people, we didn't need it before and we don't need it now
