Anyway, in terms of safety, it's safe in a way because you're doing it on a highly regulated and compliant platform, but unsafe in a way because you don't actually own any real Bitcoin, only a kind of ETP. So, you aren't actually in control of your Bitcoin.
Do you think the stock broker owns any bit coin though? meaning they own the bitcoin and you dont they just owe it to you like banks and fiat currency. Or is it just a futures market thing where there is no actual Bit Coin in there?
