So how much money

If you bought Bitcoin at $110,000 and invested $4,000, and Bitcoin increased to $150,000, your investment would be worth $5,400. Here's how to calculate the final value of your investment:

1. **Calculate the number of Bitcoins purchased**:
\[
\text{Bitcoins purchased} = \frac{\text{Initial investment}}{\text{Initial price}} = \frac{4000}{110000} \approx 0.036
\]
2. **Calculate the final value of the investment**:
\[
\text{Final value} = \text{Bitcoins purchased} \times \text{Final price} = 0.036 \times 150000 = 5400
\]
3. **Calculate the return on investment (ROI)**:
\[
\text{ROI} = \left( \frac{\text{Final value} - \text{Initial investment}}{\text{Initial investment}} \right) \times 100 = \left( \frac{5400 - 4000}{4000} \right) \times 100 = 36.36\%
\]

So, if Bitcoin increases to $150,000, your $4,000 investment would grow to $5,400, resulting in a 36.36% return on investment.
