So you are saying they didn't perform the split and they don't have or didn't have any btg at all anytime.
I found it hard to believe.
I believe they made a great profit by saving btgs for them.
That is exactly what I am saying. They did not perform the split due to potential security concerns.
It would be very easy to see if they did a split on the block explorer if they did one.
I know several people who withdrew their BTC from the exchange to perform the split themselves. Personally I didn't bother because the amount of BTC I had on the exchange was minimal and I don't like forks.
