I ask myself this. At kraken you have tier 3 where u can cash out 50k a week.
If you have like a million you want to cash out, it will take you 5 months. Meanwhile the market and value can crash already again.
Well big investors don't use exchanges that normal traders usually use because there are limits on what you can withdraw in a day to avoid money laundering, I mean they still use it but not for huge trades. What big investors usually use is cryptocurrency over the counter (OTC) trading and dark pools, there you will be able to buy and sell massive amount of cryptocurrency without any other people knowing because it is a peer to peer trade which means there is no record and every trade is private, and of course there are no limits on what you can sell and buy.
