My goal is to build up as much btc as I can this year and seeing where it gets me in 10 years, but cashing out some profits in fiat every now and then. I will pay by CGT on the amounts withdrawn, should it go over my allowance.
Bitcoin isn't just a digital currency, the technology behind bitcoin and what has spurred from it (the blockchain), is the technology of the future. We are now in the equivalent of being in the early 90's and the start of the internet. I for one will do my upmost to have a large stake at a small price in the next Amazon, Google etc.
To put another slant on it, I believe that in the future a political movement will come forward using the blockchain as a "transparency" tool to get away from the stalemate we are currently in. Just start reading, and reading, and reading and it will all make sense in a real "lightbulb" moment. Sorry if this is all a bit jumbled up, I'm sleep deprived from trading

All the best.
