Thanks for all the insight guys, appreciate it.
I ended up putting £200 on the dip.
I was dabbling in the world of trading and had my money spread across about 15 coins. I ended up keeping away from this because the fees to transfer between wallet and exchanges are astronomical and I would have to clear about a 30% return just to break even.
So my goal is now simply to invest. I see this as a savings account now with a volatile interest rate. Each month, what I would normally put away into savings I will invest half into a split of Bitcoin and Ether and just leave it like that.
I love watching the graphs and trying to gain as much knowledge as possible but I'm also acutely aware that I am not going to make a fast buck from trading unless I am an expert at it. And I'm not going to be an expert unless I invest 40+ hours a week into it. I'm quite content now just investing some cash and watching the rollercoaster from a sideline.
