I donāt quite get thisā¦ Can happily trade crypto on exchanges (some good, some dodgy) and with some online banks, example Revolut, yet cannot trade them in investing platform. I can understand it from a CFD perspective with very high volatility and leverage some can get themselves into all kind of trouble. Can even understand it from an ISA perspective with it being a āsavingsā account and all. What eludes me is why it cannot be on the investing platform which with a broker such as T212 surely offers far more protection (of sorts) than many if not most exchanges.
Well the ISA is just a fancy name for CGT wrapper so it should be the same for invest/ISA 
But I fully agree why ban ETNs like BTCE funded with your own money
FCA are painfully backward
One of the main reasons behind the FCA Ban, is because of the retail investors protection claim. As a retail investor you a have protection in case your broker goes under (I mean goes bankrupt )
The Financial Services Compensation Scheme (FSCS) is the UKās statutory Deposit insurance and investors compensation scheme for customers of authorised financial services firms. This means that FSCS can pay compensation if a firm is unable Etc.
With crypto seen as very volatile and can lead to these firms collapse there by leading to too many claims. They wise guys at FCA decided to start cutting their losses earlier before its too late and they will be left With a hefty compensation to pay out to too many unfortunate people. (Retail Investors)Thatās a layman explainlation. If you are a professional trader you can still trade Crypto Currency in UK.
