Even though I feel everyone will disagree with me but I'll raise my opinion anyways and not care...I am not always right btw but thats just how I feel

I agree with you on few points of course, but I disagree with other points...mainly you calling people who use DEX are newbies, If you consider me as a newbie which I might be then thats fine, the word itself doesn't bother me. But I held my first bitcoin by sheer luck back in 2013, I did not even know what wallet is, someone tough me how to open a wallet and I did as he instructed then received my first ever transaction. It was an xapo wallet back when it was free of use. Regardless of that I hold some coins in my cold wallet/metamask/electrum and some on exchanges as well. and I do actually prefer the exchange over my other wallets and here's why..its all a matter of person opinion.

1) swapping/selling/buying/withdrawing. Its all easier on an exchange than a normal wallet where you need to find a DEX to swap coins, approve a transaction with a fee, then pay another fee to transact. In an exchange however its noe fee.
2) p2p going in and out of the exchange is made simple, with zero fee's I can swap my coins/usdt into my countries money and vice versa, safely and easily.
3) not my keys not my coins right? but if the exchange is real solid I can trust that my coins are safe. Trust me I know what happened to FTX and other exchanges I am aware....but I didn't choose ftx 7 yrs ago for a reason, you must conduct a good research.
4) you have many options in an exchange like farming,trading,options,saving,liquidity farming.....I know i know you can do those also in a dapp farm but again its not as easy, you need to find the good dapp first, you need to double check their website everytime & see results, ultimately in the exchange its all in one place.

Meanwhile the disadvantage of the metamask/coldwallet/electrum is that if you want to do anything with your wallet its too much work, allow me to elaborate. We need to first initiate & set mind for the man/lady who will use their wallet ok? To do this we need to get out of my own bodies & what we know, and we need to get inside of the body of a man/lady who is not a computer savvy, in other words someone like your grandmother. I am completely honest here, for crypto world to succeed we need to think of these people. I am not only saying they are old and not into technology but what I am saying is, alot of people even youngster are still like that. An example is my wife, she is not a computer/tech savvy & will never in a million year could learn about transactions, hash, pulic/priv kes, trx, dapp, dex, cex, and much more.....lets be honest here guys these type of people are the majority of the world and if we don't find a way for them to make crypto useful then its no point. Let me explain more....if I give my wife or a non-tech person a cold wallet which has bitcoins, do you think they will be able to get the money out of it? The answer is HELL NO, I'm sure if today i give my wife one of my priv key she will not even fathom how to get out the coins, she probably will lose them. Thats the main issue

Lets give these people a name, "The majory of the public (TMOP), so if these TMOP guys not come into our space with the ease of use, then it's our loss. How do we get them in? to use some systems that are a little bit like banks, I know the main idea of bitcoin is to move out of the medium/middle man but its very difficult, we have to have middle man (CEX), to make it easier to use and safer for the TMOP.

You may ask, how is CEX SAFER for TMOP, its the opposite right? No for them IT IS safer to be in CEX than their own priv key trust me.

For them they could be easily hacked using a wallet, they could have all sort of stuff in their computers, they could connect to a bananacakeswap thinking its panecakeswap and click "Connect" how would they know? they wouldnt, again I know you would know, but you have to get out of your own body and get into their body to see from their perspective. these fellas can easily click transfer and lose all of their coins thinking they are getting airdropped something from a telegram message.

Listen, when these people go to a good exchange with good safety record & with having 3 different safeties such as "password + 2FA + email confirmation", then they dont need to connect to any other website ever. Plus they could just stay and see what the exchange offers, then p2p get their money out of it at any time. Also they can install anti-fishing seed inside of the excahnge, so now they have 4 safeties & never have to check any website/connect anywhere, just stay in the exchange until they cash out.....thats what we need.

I am sorry for the long post but as you can see I disagree with 90% of you guys for the above reasons. I just want cryptocurrency to get bigger and this is the only way. Otherwise it will be "Crypto-scammurecy" instead of "Cryptocurrency" which it already is a big scam space if you think about it, and where do most the scams happen? In telegram with metamask approving/connecting thir wallet to places thinking its another place type of people. Its painful to see.
