AI Bitcoin trading algorithm

I have been testing and backtesting various Bitcoin trading algorithms and I came across a particular model that performed huge rates of return in backtesting, we are talking about ten to the power of 17 and above in a year returns. I set a robot in motion with this model with a minimal stake and it came out negative in the 3 weeks of testing. I plotted out the backtest for a year including the real world period I used in Power BI and I noticed that there are continuous period where the outcome is profit (in the chart look at the light blue line - sum of profit percent), and continuous periods where the line is negative. I have tried to look for various correlations but I am out of my depth. I have attached some sample backtest data also to this enquiry.

I therefore would like to get a quant to help me work out what is going on, and to help me realise the potential profits from this model. I want to keep the model secret, and not divulge it, and so would make it available via API. I am happy to be charged for the work, also if a competent quant wanted I would be happy to make an arrangement based on a percentage of profits for the first year, or combination of fixed change and percentage of profits for the first year.
