How many of you have tried to cash out 100k or more?

I'm curious how many of you have tried to cash out a large lump sum in one go?

It seems people think this is standard, oh I can just take 100-200k whenever I want from said exchange but that has not been my experience, if you want to pull alot of cash your going to be subject to limits and time frames which obviously hinders your ability to sell all at high prices.

You also get the exchanges playing games during times of hi volatility, where they wont even let you sell regardless of how much USD and set time limits.
