They operate in 100 countries, have 30m users, support trading in 360 coins PLUS a load of derivatives on top and process $15bn of trades per day. And they are not just "an exchange". They are also custody, clearing and settlements. Frankly I am amazed they are only 8,000.

Idk...throwing around big numbers, implying confidence does not convince me. Also your numbers are mostly not neccessarily related to the amount of workforce needed.

For example my blog/website operates theoretically in all countries on the world ...still it's only me needed. I think you get the point.

I think a measure like active users is more related to the size than number of countries and coins/tokens ...

But it is true I focused a too much on the platform itself etc. They have a lot stuff going on around it for legal, kyc, regulations, Marketing etc ... The operation of the platform itself is probably not the biggest part of their business anymore.

But coinbase for example, does it with less than 5000 ... But probably not so easy to compare
