Nealy half of almost transactions involve money? I would have thought almost all transactions involve it, in some form or the other. You can have barter transactions, but I doubt if they would be significant in the larger scheme of things.
It could be worded better, but I interpreted it as "nearly all transactions use money as one half of the transaction and exchanging for goods or services as the other half". Barter trades are the ones that don't fall into that "nearly all" category. It seems as though the second sentence is intended to clarify the first. I'm pretty sure they're not suggesting that half the world's trade is barter.
But they are suggesting once again that BCH is the "true" Bitcoin, which doesn't really seem to be borne out in reality, still effectively only able to operate at ~16% of Bitcoin's difficulty and only having ~20% of the total nodecount of Bitcoin.
