You are right, I should've checked prior to posting! I was paper trading GDAX (end of 2017) and they were charging about 0.2% for taking liquidity and nothing for providing it. My strategy was mostly taking liquidity, so wasn't good for me. Plus all the other stuff that was mentioned earlier, just wasn't worth the time for me.
It's too bad that the underlying cash market in crypto isn't more liquid and robust. I would be very interested in trading the futures if that were true.
Ah, you mean the broker/dealer who got sued by the CTFC because it operates as an unregistered and unregulated foreign exchange dealer?
It would appear that you need to add "register as a legal trading exchange" to your list of key features in the thread OP. Looks like the SEC and CFTC are cracking down with a vengeance.
Most of the stuff you guys have mentioned as missing are available as 3rd party tools available. Then again, maybe 1% of ET'ers actually trade crypto.
No idea about that but I have been using them for over a year with no issues. Have you used them or just going off things you read on the internet?
I go off things I read on the internet. Especially this website: https://www.cftc.gov/PressRoom/PressReleases/7765-18
What are the key features/tools missing from Professional Crypto Exchanges? Honestly speaking, NONE of the above. Just focus on chart and that is more than sufficient.
