Thanks for all the replies, I did get some in the end and it's gone down since I bought some.
I also have done alot of reading on cryptocurrencey and I do believe it is the future of money.
Not sure how true that is, fiat currency used to be backed buy the gold standard so it was worth x amount of gold but not anymore and because it's not backed by commodities I would say it's limitless, so the government's can just keep printing more and more.
Bitcoin has a maximum of 21 million, there can never be anymore....ever.
To create a bitcoin you have to mine it, which comes at a cost of hardware and electricity and every few years this cost increases.
I do think it's still very early days though and because of this it's very volatile.
