At one point it was suspended for a few months.
I think that SEC "hates" it.
Or, maybe BS has these feelings, lol.
Honestly brokers have fucked around on XBT's ETNs to the point that I feel there is some behind the scenes fuckery going on.
Example: Interactive Brokers used to not allow trading on GBTC at all, but actively put out news stories that they were trading XBT. Then when their own BTC futures came out, they stealth blocked XBT trading. Not only that, they planned on dumping everyone's XBT by a certain deadline.
Interactive Brokers is known to dump accounts without limit orders. They were probably sitting on the other end with a fat buy order as they knew exactly how much XBT they would be dumping.
I don't even think they sent out email messages on their plans to delist and dump as I only knew about it by randomly logging into my IB account. Based on the date of the system message, they only gave like a 2 week period between notice and dump.
Same thing with Fidelity. Several news stories were out about them offering XBT trading, and they still offered them for trading even after IB blocked them for a bullshit "not registered under some SEC 1933 act." Now Fidelity is planning to launch their own crypto trading (I think it's active for institutional investors already) and they've blocked XBT. Bullshit yet again.
