RE: So with the BitCoin system of competing “miners” trying to be the first to reconcile a long chain of transactions, how many transactions per second can the BitCoin system sustain?

Who has that kind of computing power eventually?
14,765.18 Terra Hashes / second, with more being added by the minute.
