I actually had a similar scenario, having Sunday Dinner with my dear old Dad, and my alerts all go off at once... my MAIN HODL COIN rips past all my alerts, but I have like 95% of it staked. FINE, I'll just sell the 5% IN WALLET and HODL the rest, the divs will be AWESOME!
Hoping this crappy photo upload is working so I can upload the pic... screen shot of my $2.5 Million!

Nope POS still not working, let's try this:

So the bad news is that I was unable to sell, and then he news came out that it was an attempted exploit of the crypto Dot com Exchange... Haxors had found a way to HFT (hi-frequency trading) manipulate the price of ETH to around $65,000 but were unable to sell. So while I didn't get to sell, neither did the bad guys. The exploit was fixed and no funds were lost. That's the benefit of being on a USA compliant coin exchange...

😅😅😅

But I did get a real glimpse "what would YOU DO" if you were suddenly RICH. I expect I will experience that later this year, maybe not as sudden as that or your Scenario above, but I am positioned for 6 coins that are poised to explode at least 30x and more, if the top level INTEL pans out. It's prime Fundamental analysis from one of the best track records in the business. Plus, these are all HODL and have dividend payouts. Patience is a virtue! But I need a plan to roll out some profits, into less volatile funds/vehicles.

Great "what if" thought exercise, and I have a plan in place!
