NOT FINANCIAL ADVICE!!
The way this economy is looking right now, it wouldn't hurt to store some extra currency in a safe place. Financial institutions use digital currencies / Cryptocurrencies to make transactions from one to another. Some people store money into metals, which is also not a bad idea, but not everyone can afford that. With a little research, it isn't hard to determine which is the best crypto for you. Whatever your investment is, it's just as important where you store it.
