Purtle, I am really sorry for the loss of your coins. I can not imagine anything worse happening.
I assume your point is urging owners to transfer their coins from the exchanges to their wallets as soon as possible, and that certainly is great advice as nobody will be able to take them away from you, you will own them with confidence
However, let me share my latest experience with a major crypto purchase that went badly.
A few weeks ago I bought a large amount of a coin, with the idea of holding it (or going long on it) for a couple of years, at least.
I believed strongly in it (and still do), did all my homework: Fundamentals, tech analysis, team reputation and experience, whitepaper, reviews, team interviews, etc,etc…It all looked great.
Almost immediately after buying it, the coin went up more than 30%, so I took this as confirmation of my extremely clever purchase and proceeded to move the coins from the exchange to their wallet, with a big smile on my face.
Just a few days afterwards, the same coin began crashing seriously. It was so bad and so fast, that after a couple of days it lost almost half of its value,and now I am stuck with it until it improves a bit and I can get rid of it: A trader’s worst nightmare.
Now imagine that instead of rushing from the exchange to the wallet I had left the coins there for, at least one more month with a stop loss order. None of this would have happened.
So, from now on, as an extra financial security measure, I will always keep my newly purchased coins on exchanges for at least a couple more months with stop loss orders to prevent those drastic and unexpected trend reversals. Only then will I move them to the wallet.
As a conclusion, it is a very good idea to move your funds from the exchanges towards the wallets, but you might want to keep the coins in the exchanges for a few weeks with stop losses orders triggered, just in case…
I hope this disaster will at least help preventing someone else to go through the same thing…
