Rate of return for the next decade?

We now know that bitcoin will be added to many portfolios as it can oddly enough "REDUCE" volatility and add an uncorrelated part to your portfolio (more correlated as of late however we need to look 5 years out)

Has anyone calculated the rate of return bitcoin should expect per year? Seems like 100-189% should be the average. Obviously it could have larger increases and of course 50-70%+ declines.

But just like the benchmark S&P has close to 10% what can we expect bitcoin to return over the course of 5-10 years so you can position your portfolio accordingly.

edit: eventually returns should diminish to close to 5-10% as this vehicle matures....the years of super high growth of 11,000%+ seem to be over while it should churn out triple digits one would expect those to decline over the years and become quite stable
