Hi,
The idea is to buy a diversified portfolio:
When Bitcoin goes up, X goes down.
When X goes up, Bitcoin goes down. You need to make sure you have X and Bitcoin.
You also want to make sure that you have traditional stocks as well as fiat currency. I really like the advice by Dave Ramsey when it comes to the latter two, though I suspect he hates cryptocurrency.
Here's an example portfolio:
25% BTC
25% LTC
25% XMR/ZEC/XMR/STR/etc (basically the hedge to BTC/LTC)
10% cash
5% physical money
10% traditional stock
