This is my first and last attempt at data analysis.
Starting from April 2020 - October 2023
If you'd put away £225 each month for 150 litres of fuel, and then paid for the fuel the following month, with the previous months savings, you'd be left with -£236.84 for Super Unleaded, £575.22 if you're a savvy Premium Unleaded guy and £50.09 for good ol' Diesel.
Now if you didn't have to pay for fuel and saved all that dough, you'd come away with £9,675.00 which is not bad, not bad at all.
But what if there's a better way?
SPOILER
You guessed it, it's Bitcoin. Doing the same in BTC terms would leave you with 0.02814193 BTC (£789.97), 0.07161600 BTC (£2,010.33) and 0.04254737 BTC (£1,194.34). If you didn't have to pay for any fuel and saved all that sweet corn you'd be left with 0.53612105 BTC (£15,049.40).
Time to get savvy, savers
