All of them makes huge sense to me. All are old beside Binance. Binance was just super lucky with its timing and also works good. So is not just luck, but still a lot of luck. You cant fail with any of these exchanges.
Binance had some luck with the momentum they had going for themselves, but the most important aspect is that where their brave compliant competitors did everything to not break any laws where they offer their services, Binance just didn't give a shit and entered as if it was their right to settle there.
IIRC, Japan has been the only country actively trying to make Binance comply, but for whatever reason, Binance chose to halt their services in Japan and exit entirely. Such a large and successful exchange has no problems financially covering all the costs, so there must be other (potentially shady) reasons they didn't want to register and get themselves audited.
On the other hand, they are very important for Bitcoin because all the altcoin and ICO shit there increases the demand for Bitcoin because that's what most people use to trade.
