Actually Bitcoin and crypto currencies are not required/unwanted
The concept of cryptocurrencies/Bitcoin is to get away from the fiat banking industry. All of your examples above are still within that industry and rely upon government paper. Cryptocurrencies are just that, currencies. An alternate to government/bank controlled fiat paper. Governments don't like this concept and have classified cryptocurrencies as assets and not currencies to rival fiat paper notes. Your mindset should change to the fact that they are currencies and not assets that can be invested in. Currently the hype that noobies have come in over 2017 is that cryptocurrencies are assets and base it off of their native fiat. With the growth in the exchange rate they have come to see them as assets, like precious metals, and have "invested" in them. This line of thinking has contributed to the wild swings in the exchange rate to whatever local fiat is applicable.
That's right. It's a different kind of currency and market asset that can be used for many different things ranging from trade, investment, holding, and all other ventures that may lead to you earning coins or tokens. And since part of the title of the thread is safety, I am not sure if there is a true blue safe way of earning in this market because the market and its assets are just characterized for their risky nature that it is often moving in a volatile manner where price changes is an everyday thing. The venture you should choose should depend on what you can commit to and what you feel you can earn from.
