How do you track crypto alongside your other assets (metals, real estate, traditional)?

Been stacking BTC since 2019 alongside physical gold and silver, plus some real estate. Each asset class lives in a different tool — wallet for crypto, spreadsheet for metals, sponsor portals for real estate.

Trying to get a single net worth picture that updates automatically, shows allocation percentages, and handles the fact that crypto moves hourly while my real estate updates annually.

Curious what the sub uses. Specifically:

• Do you even try to integrate crypto with other assets, or keep them separate mentally?
• How do you handle cost basis for BTC bought across 5+ years and multiple wallets?
• For self-custody, how do you make sure your heirs can actually access it if something happens to you?

Last question is the one that's been bothering me lately.
