My money is invested in my business. Just moved premises at great expense, so not allot of money lying around for bitcoin investment right now. But your right, if there is such thing as a safe investment in this day and age, then I dont know about it. So Bitcoin is one of the bester options, or perhaps guns
Guns aren't bad - one of the last bastions of fine machine work. And useful, on occasion.
Long-term, you might want to think about rare wood, too - if you have the space and proper atmospheric conditions to store it. Padouk, zebrawood, amaranth; like that. As climate change and deforestation in the third-world areas where most of it grows take their toll, the stuff has been gaining value very nicely.
Wood far outperforms most investments; and has, for as long as I've been paying attention to it. It doesn't outperform bitcoin, of course; but it
is diversification.
Sad cause, but interesting investment advice.
