I found the part of the table addressing Bitcoin transaction times really hard to understand. Also, while I agree that transaction times and fees of Bitcoin are high, either can easily be compensated for by the other: Paying high fees gives low transaction times. In that sense, only one of them is a problem (Since so many use Coinbase these days, high fees are automatically selected, providing acceptable transaction times). I wonder how the transaction fee/time ratio would have been if Coinbase wasn't around.
