To me there is nothing else that you can store your wealth in that benefits the world as greatly as Bitcoin without supporting the current system of extracting value from others which I view as morally bankrupt. The benefit of "massive gains" comes with the cost of dealing with volatility. But if you're very patient and live frugally with minimal living expenses, then the volatility isn't worrisome when you know your savings will grow exponentially over time.

And I do know it will grow with time. It is functionally guaranteed to grow 14.99% a year from the exponentially growing energy input of the mining network, and another 18.93% a year from the value doubling effect the halving has on the coins relative to the mining network cost of production, as well as 6.8% a year tracking the rate of USD debasement. All in all Bitcoin is guaranteed IMO to see 46% average annual growth as measured in US Dollars across 4 year periods.

This is assuming the previous 6 year average, of 15% annual energy input for mining growth, continues to be seen. We know for certain that the USD will continue to be debased, and we know for certain that the halving will occur and reduce the amount of coins earned though proof of work every 4 years until either 2140 or in perpetuity. So the only variable is the mining network, which will likely continue to grow because nothing else pays humanity for otherwise useless energy. The value of energy without another use is no longer wasted as it can be sold to Bitcoin miners. This builds energy abundance like never before, and Bitcoin preserves the value of that energy like never before.

Bitcoin is freedom for all mankind.
