The strategy of 10 years cumulative return 60k times max drawdow

BTCUSD
I have studied 10 years history data of Bitcoin. And I have done the Linear Regression with a fundamental factor. The prediction accuracy of Bitcoin price is 88%. 10 years cumulative return 56k times. If you invested in this strategy for 10k$, you will get 560 million US dollars in 2021. The max drawdown is 62%.
The blue line is alert indicator, the red dotted line is selling alert upper, the green dotted line is buying tip lower. When the blue line reduce lower the green dotted line, you should buy. When the blue line rise above the red dotted line, you should sell.
The startup capital in 2011 is 10k$, the final capital is 600 million US dollars in 2021. The cumulative return is 60k times.
The purple line is max drawdown percent, the max drawdown percent on 20th March in 2020 was -62%.
If you used "buy and hold" strategy, the Bitcoin price on 24th August in 2011 was 11$, it was 54244$ on 8th October in 2021, the cumulative return was 4931 times.
The Bitcoin price on 14th January in 2015 was 152$, comparing with 1163$ on 30th November 2013, the max drawdown percent was -87%.
After all, this strategy is more return and less risk comparing with "buy and hold" strategy.
