I started back in 2017ish after hearing gold going to £10k by Jim Rickards🎣. I am glad I got into PM's as it allows me to save as I was and still am terrible at saving.
As Stu mentioned earlier you will be surprised at how a stack can quickly grow just with small purchases a month. Key is to stay in your lane and buy what you can whenever you can.
I bought a standard bullion Sov at £360 which is at a loss ATM but also have bought a standard bullion Sov and £240. My point here is to pay little attention to the daily fluctuations and allow the bigger picture to take over.
Gold and silver are long term plays and if your happy about that sort of time scale I believe in the metals.
