# If you trader never trade with one exchange use 3 to 4 exchange and divide btc with 3 or 4 parts
What's the reason behind this advice, personally I have used multiple exchange for trading but there's just one that I enjoyed more and assuming I decided to chase a career in trading I don't mind using only one exchange for that if I'm getting exactly what I want. Some exchanges might favour you why other don't. Truth be told, not all exchanges are being honest, there are definitely some unfair activities going on that involves the manipulation of the market. Staying with one exchange has its benefits and the cons mightn't be that bad, probably like the exchange having down times when you want to trade.
In fact, using an exchange is very risky, because
If the exchange has problems due to any restrictions and policies or a group of big hackers targets the exchange by stealing the exchange's information, or at any time any employee, owner or worker of any exchange can resort to dishonest means.
(So just as putting all your eggs in many baskets is less risky, we can also view the exchange as basket, where there is less chance of all the baskets having problems at the same time and there is less chance of problems happening together)
