First you should choose between weed and mining.
If you choose mining make your way to the mines asap and start hitting those rock here is my knowledge of ore prices
bronze is £500, silver is £900, Gold is £1,900 and Platinum is £8,500 (For the love of your belief tell me if im wrong)
I think 1oz of weed sells for 27k i am not quite sure.
In conclusion weed is worth more but is illegal mining sells for less but isn't illegal
Thanks for reading this far!?
