Real Estate is tested and proven over centuries to provide the opportunity for wealth with crashes once every few decades and Bitcoin is a unproven cryptocurrency that uses block chain technology.

Basically, I need to transfer a big amount of money to the states, and convert it from the currency we use here (New Israeli Shekels) into dollars.I was wondering if anyone here at bigger pockets has experience or advice how such a thing could be done safely and cheapest as possible?

Use cryptocurrencies.

I was expecting you to pitch crypto currency at the end of that post 😂

Read an article about a Texas home being sold for bitcoin, and this gave me an idea.I personally don't buy into bitcoin or any cryptocurrencies, but I see an opportunity of turning crypto into cash instantly.Sellers can pay a premium for accepting crypto transactions for their listing, but will receive premium price for accepting crypto from buyer.

is/has anyone buying cryptocurrencies with their IRA account? 

Same thing with crypto or any investment that runs up.

I have multiple mortgages, banking accounts, credit cards, brokerage accounts, crypto currency accounts, crowd funding accounts, employee 401k, self directed ira, employee stock plan administrator, shares in a small-town bank, I feel like I could go forever.

All pumped by money that people don't have, created out of thin air by the fiat currency system.. 

Look at it as a $100 bill, the largest and most valued currency for US.
