I think I'll give it a miss.
The main issue I've run in to is that some banks refuse to allow people to buy bitcoin, sadly my bank is one of them.
The way some people get around it is using another mobile app bank (Revolut is mentioned a lot) to transfer money in to there, then from there to the bitcoin exchange. It all seems more hassle than its worth at the moment.
Hopefully it'll become more accessable, especially if Paypal bring the ability to invest in to bitcoin to the UK. I think they let their US customers do it.
So I'll pass on this one, especially when you said its very risky anyway. It doesn't sound like its worth the hassle.
