I want to think that people who still store their Bitcoins in a centralized exchange and continue to do their transactions or just save it there either one, do not know the inherent dangers or two know about it from the stories of others and are living in a fantasy they can't lose their Bitcoins to exchange just like the others. Or maybe they are trying to be smart like wanting to save some money on the transactions fees involved in sending Bitcoins from their wallet to their exchange app whenever they have to do a transaction.
I often take it to be a deposit for the purpose of trading these Bitcoins and Altcoins for the long term of short term, swapping it or engaging in some p2p trades but over time, you find people building comfort over the fact that, these are rare occurrences that hits once a while and with you to have not been a victim, it gives the idea of the exchange being used to be very secured. It’s always just a matter of time and you are a victim, the principle of not your keys not your coins should be a fair warning.
what most of the people that find exchanges to be a secured storage for their Bitcoin don't understand is that, cryptocurrency is all about freedom and Decentralizations, this make it important for them to put measures in place that build up that freedom.
Security without freedom is somewhat not complete satisfactions and that have a lot to do for a Bitcoinnaire or crypto pros.
