A friend of mine originally planned to buy a Tesla Model 3 with a full payment of 230,000 yuan. After listening to the calculation I made for him last time, he changed to a loan plan.

He now uses 80,000 yuan for the down payment, and the remaining 150,000 yuan principal is directly used to run the BTC spot grid (using the grid strategy tool of OUYI).

1. The price range is set at 57,000~79,000, and 88 arithmetic grids are set;

2. The price difference of each grid is 250, which basically captures most of the fluctuations of BTC;

3. The configuration grid moves down to a minimum of 47,000 and a maximum of 95,000;

4. Regardless of floating profit or floating loss, the monthly rate of return is 2%~4%, and the monthly grid arbitrage income is withdrawn to pay the monthly payment.

If BTC does not fall below 47,000 within 5 years, he will pay off the monthly payment and the principal of 150,000 will still be there.
