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.
Some of my friends every month cash out something about 10-15 thousands dollars every one. I heard that one of platforms they use it is Cex.io. I have no information about if it is possible to cash out sums of money that are bigger.
