Given an investment that will double forever your investment and money in the bank with the 20 percent rule will be, starting with 100:

Number of doubling: 0; Invested: 100.00; Bank: 0.00; Pure HODL: 100; ratio: 1.00
Number of doubling: 1; Invested: 160.00; Bank: 40.00; Pure HODL: 200; ratio: 1.00
Number of doubling: 2; Invested: 256.00; Bank: 104.00; Pure HODL: 400; ratio: 0.90

Generated with:

investment = investment0 = 100
bank = 0
pure_hodl_ratio = 1

percentage_to_sell_at_each_doubling = 0.2
for i in range(20):
print(f”Number of doubling: {i}; Invested: {investment:.2f}; Bank: {bank:.2f}; Pure HODL: {investment0*2**i}; ratio: {pure_hodl_ratio:.2f}”)
investment *= 2
bank += percentage_to_sell_at_each_doubling * investment
investment -= percentage_to_sell_at_each_doubling * investment
pure_hodl_ratio = (bank + investment) /​ (investment0*2**i)/​2

You can change the 20% to another value, 50% is a critical value to stay below.

Not investment advice, have fun with this.

Reasonably you’d probably skip the first few doublings for something that low value, which changes the outcome significantly.

[Caridorc Tergilti]

Yes a doublingsToSkip variable, where the 20% is withdrawn only if i > doublingsToSkip would be an interesting addition
