Is OTC beneficial for large-scale traders i.e. sharks or whales; whatever you want to call them or is it a safe haven for small traders.
Beneficial in a sense that it won't affect the price specially if you are buying huge amount of bitcoin. Of course there is the privacy in which whales wanted to keep as a safe guard for them.
I haven't heard any small traders doing some OTC, small traders or average joe's just go to the usual route and it makes them comfortable as opposed to some big entities who's moving huge amount of bitcoin in the market and OTC is the best way for them.
