Many people have offered you advice on where to buy bitcoin and what precautions to take when trading bitcoin on a centralised exchange. Don't ignore this advise; if you don't, you'll end up up losing most, if not all, of your funds in a centralised exchange. You should now understand why centralised exchanges are not recommended for leaving your funds on; individuals who ignore this always end up regretting for their careless behaviour.

And you should now understand why decentralised exchanges are the ideal way to save money if you don't trade frequently. The disadvantage of this type exchange is that when you reveal your private key, your funds are lost. Privacy and security is important in cryptocurrency and you don’t have to joke with them both.
