But I can't help but think about the currency inflation the Federal Reserve and government have been pushing the past few decades.

When I study the hyperinflation of the Wiemar Republic after World War I (When Money Dies by Adam Fergusson), that hyperinflation was brought under control by backing the German currency with mortgages because the German public had confidence in them.Study Warren Buffett's presentations (Warren Buffett MBA Talk, a 90-minute slice of heaven if you're a value investor).

We're looking to build long term wealth and passive income.We have US bank accts and are actually paid in US$, so it's not like we're actually a foreign borrower with currency risks. 

They could be mining cryptocurrency on their computer.

My husband has been investing in cryptocurrency and has really enjoyed it. 

You can invest in real estate, private equity, trust deed, tax liens, precious metals, crypto currency, and much much more.Few considerations: With custodial self-directed IRA you would have to go through IRA custodian for each transaction (you will have to deal with delays, bureaucracy, red tape and asset/transaction fees). 

I have been involved in this cryptocurrency bull run and have a lot of capital I'm looking to invest in real estate that is cheap and in countries with growing free markets.

I was wondering if anyone had info on reinvesting crypto profits to avoid capital gains tax.

We currently rent a cheap apartment and are just stockpiling our earnings (investing in crypto, should have in DOGE lol jk) to save up for a purchase so that's not a bad idea to get into house hacking prior to investing in other properties. 

I'm now investing relatively small amounts in cryptocurrency and I've made the decision to have 10% of my net worth in various blockchain technology assets.
