Inflation will happen and at this rate the US dollar won't be the world's currency forever.

IE real estate, business, crypto, budget...

A short lesson in economic history:  The US dollar is the de facto world currency and has been basically since WW2.  

The statutory definition of securities is as follows:The term “security” means any note, stock, treasury stock, security future, security-based swap, bond, debenture, evidence of indebtedness, certificate of interest or participation in any profit-sharing agreement, collateral-trust certificate, preorganization certificate or subscription, transferable share, investment contract, voting-trust certificate, certificate of deposit for a security, fractional undivided interest in oil, gas, or other mineral rights, any put, call, straddle, option, or privilege on any security, certificate of deposit, or group or index of securities (including any interest therein or based on the value thereof), or any put, call, straddle, option, or privilege entered into on a national securities exchange relating to foreign currency, or, in general, any interest or instrument commonly known as a “security”, or any certificate of interest or participation in, temporary or interim certificate for, receipt for, guarantee of, or warrant or right to subscribe to or purchase, any of the foregoing.

I've been trading currencies and investing in stock options since I was 14 years old.

This site is great if you are looking to invest into real estate, wholesaling, flipping, rentals, lending, self-directed IRA and Solo 401k investing, crypto, or tax and legal guidance.

I also recommend you study past and present economy and fiat currency (good lord, this is boring to me, but so important), to better understand what's happening and where our economy is going- as it will help you invest wisely, and understand crash/boom timing.

Comparative to your market.Currency vs currency impact?

For instance, when I started I only narrated books about real estate, stock market and crypto.

@Nathan Asher Robson I would look into currency hedging products.
