Welcome! That was a good start with 0.5 ETH for GBP 5,-
Hopefully you can make more steps like this :)
My best tip: Do your research of a coin before investing in it. Search news items on Google, people talking about it on Youtube, etc.
That gives you the best foundation to make a decision for investing in a cryptocoin :)
Good luck mate!
