I dont know why i should not keep my coins in exchanger if i am carefully then i think that nobody cant stole my money from my wallet so i keep my money in exchanger really long time and it is still there in exchanger.
well i guess you didnt learn about the bitfinex hack, it should be never done because no one knows what might happen
That's why i never keep my bitcoins on exchanger, it's really risky because they can take your coins or a hacker hack that exchanger sites like happened to bitfinex.
Many people like myself use the exchanges for small amounts. I never have more than $100 dollars on any exchange. They are convenient in many cases for my trading. That being said I also have to agree with you. People need to know that they should be prepared to lose their coin if they keep it ALL or even small part on an exchange.
