You can't beat stocks over the long run. Gold and gold coins are just something to have as disaster insurance and/or to have fun holding in your hands. Even bond funds aren't bad right now, 6% give-or-take for investment quality ETFs.
I moved out of stocks about 5 years ago and converted that in to BTC, which is doing outstanding ! I have been able to keep the principal intact while taking the "FOAM" of the top which I have been using to buy both GOLD AND SILVER been averaging about 5K a month just on that investment alone
Putting all your eggs in 1 asset class....a new one at that....which is highly volatile and pays no interest or dividends....borders on reckless, IMO.
When it gets to be reckless I will let you know, And BTC kicks butt ! for all the doubters out there, here's a small sample of what I picked up last year, just on "FOAM" alone havent touched my principle in over 5 years and still going strong ! P.S. Can I please get a like from you @masterswimmer .....LOL
