There are a lot of OTC bitcoin brokers nowadays but the most trusted around is itBit and Circle (though I'm not sure with the latter if they are still offering such a service).
There is also Genesis Trading (some shady stuff going there, but which one is 100% clean.. ), B2C2 and Bitpoint.
But many exchanges will also offer OTC, Kraken is known for such deals.
I would really appreciate the help for any info on the personal experience or any articles. I am trying to do one research on that for educational purposes.
You won't get precise answers here, unfortunately.
Everything depends on how much you want, their current balance and how many standing orders they have.
One might offer you a better deal today for 1000 than another tomorrow for 5000.
The only way to get some reliable data would be to try and contact them and act as a seller with a small to medium stash and ask for some numbers.
You're the person that does not know what you're talking about. Clarify what bullshit I said. You're the person that's not experienced OTC since you're a newbie
. GCOX has an OTC exchange. I manage to invest some in there and they literally have no sellers in there.
Nope, you're the one who has no clue what he is talking about.
That thing on GCOX is a fake p2p exchange, nothing more, but they've labeled it OTC to attract more morons to their ICO.
