I used to be the biggest believer in BTC and cryptocurrencies. March made me a huge skeptic.
There is simply too much downside to BTC at this point. As we saw in March, any massive market correction will take down BTC gloriously. BTC dropped 50% in one day, alts flashed to 30% of their price in one day.
If you're bearish on the stock market, I'd stay away from BTC. It's very difficult to instill mass institutional confidence in an asset that has that level of volatility in a worldwide depression.
You haven't considered many, many variables that all counter your position. Deflation is the first. Inflation is the second. Hyperinflation is the third. For example, the March move down (with gold) is easily explainable --- and there are many reasons why that will be less and less common in the future.
