If Bitcoin price pumps from $1300 to $3000 in few hours, nobody would make profit from it, because the exchanges wouldn't allow you to sell your Bitcoins and make the fast profit, it would bring a big loss for exchange sites.

Do you agree with this?

If exchange itself is not trading, they basically don't care

More specifically, they care for fees, and trading fees obviously come from trades, so when there are abrupt price movements the trading volume spikes too. And it doesn't matter whether the price flash crashes or flash surges. So, they are in fact interested in volatility and price being "alive", therefore prices pumping to 3,000 dollars per coin would provide exactly that, i.e. insane levels of volatility

This is actually right. Exchamgr are having profit from transaction fee and they are not the one who buy and sell the coin you are trading. The devs of the coin is the one who is giving funds for the exchange to cover some buy/sell order and the majority of the order on exchange came from different traders too. So having a flash punp is not an issue for exchangr

It really is not an issue for an exchange and reputable bitcoin exchange sites would not dare to scam their users since they will lose there their constant flow of income from fees which have high volume sometimes. You only need to be worried of scam to their users if the exchange you are using is not that reputable and is not that well established yet and have low count of daily transactions to sustain their website

This has nothing to do with scam

Exchanges just make use of an opportunity to earn risk-free profits whenever such arises. They don't steal from their clients in a direct way. In fact, they may be even providing a somewhat better price for an incoming order (hence, front-running), though the difference will likely be infinitesimal (i.e. the lowest possible at this exchange). Even regulated, most "reputable" exchanges from the real world are regularly caught front-running the orders of their clients, and that's considered illegal by the regulating and supervising agencies and commissions
