discussing trust Holding your keys is simply the best option when it comes to cryptocurrencies, security of your funds should be the number one thing you consider, and people have always warned against trusting an exchange. I don't think, I wonder why people will so much put their trust in exchanges, not only CEO but also individuals, anything centralized I don't like, talking about banks I wish I was a legislator banks are just too annoying the way they operate is just too selfish, and holding your keys is simply the best option. keeping it safe matters a lot.
There are differents instances concerning risk if an investor would be storing assets on exchanges such as other people being able to easily access yiur device and transferring funds. Another one is if you are trading without stop loss (perhaps you forgot to do so) wherein other money in the bag could be lost with it once liquiation has been reached (I've experienced such thing in Binance Futures, but that's my fault). Well these are only practical scenarios and just pointing out exchangers are not storage of wealth.

below the market is a place efficient miners acquire coins.
if no one on the planet can get coin for less than this.
nor wants to sell below acquisition cost.
then the price cant fall to zero

I'd agree with not your key not your Bitcoin even if it would be seen on your transaction. Once things are transferred it qould be hard to get it back because no one would regulate it unlike with centralized online wallets. You'd only be able to know which destination your assets came.
