We learned that many blockchains technical limitations that prevent transactions from settling in real time (for example, you must wait at least ten minutesusually longerfor your Bitcoin transactions to be verified and appear on the blockchain). If this is the case, then how are so many people able to trade bitcoin in high frequency?

A.They pay much higher transaction fees to the miners to get their transactions processed faster

B.They directly control more miners and therefore have a higher computing power

C.On the exchanges, they are not trading the actual bitcoins but exchange balances of bitcoins. These trades do not involve the blockchain at all
