I proposed a permanent portfolio back in January that includes Bitcoin on my personal site: https://sanzprophet.com/2020/01/bitcoin-plus-harry-browns-permanent-portfolio-a-mix-in-heaven/
If there is demand we can incorporate and track it here at LI as a portfolio.
As for guidance I’ll be glad to help our. An easy way to start is to open a Coinbase account and just transfer funds from your bank or broker via ACH, then buy Bitcoin. Other options include Gemini, itBit or even BlockFi (pays interest on you holdings). If you have access to futures you can also buy CME’a future contract.
Of course you can eventually hold your own BTC in a hardware wallet but starting from a U.S. regulated and reputable exchange is a good start.
