It is worth keeping a % of portfolio assets in BTC (like gold, as advisers will tell you, up to 10%).
Supposedly the best peforming silver and gold allocation over time is 25-30%, not the 10% number people toss around. When every asset on earth is in a giant bubble except silver and gold, and the world economy is on the verge of blowing up, going higher isn't a bad idea when there's no other good options anyway.
