I was going through some materials when I saw Bitcoin node. Now my question to the community is; can I make money if I decide to run a Bitcoin node?

I had an encounter with a group of people who claimed that the term "crypto" and "cryptocurrency" have no difference and that they're the same thing.

At first, I thought maybe crypto is the general term while cryptocurrencies are those types of crypto that can be used directly to pay for a service like for example BNB, ETH, usdt, etc.

Is there a difference between both terms?
