+1 - Until the high fee and network congestion issues are solved, this is no different than a traditional bank. The whole point of a virtual currency is dissolved by these hurdles. If the core team doesn't act quick, its not far before LTC/XRP take over the market with their super fast network.
From the top of my head
BTC = 7 transactions a second
ETH = 15 per second
IOTA = 100 per second
VISA Card = 25,000 per second
Block-Chain is a disaster and does not scale as we can see
We need big brother and bankers out of the loop but that does not mean we need 80,000 machine all keeping a
copy of a data 200gb structure that needs processing from start to end to calculate if a wallet has the coins/token to spend.
Keep going like this and BTC will still trade but it will all be based on fake coins like Coinbase is using or we will end up
with a flood of paper type gold tokens trading at 200:1 to physical gold.
