Our privacy is not totally guaranteed with this centralised system and that's why many people lose their hard earned money to yahoo boys but with decentralised, the security is top notch.

Imagine getting charged even when I receive money from people...they indeed have a lot to work on because I can save with them again not when I now know crypto.
