You are very correct except that you didn't mention problems you need to look out for. One of this is that once you join steemit, you need to keep your password secret and only to yourself. Your steemit wallet could be tampered with if you do not. This will make you look like you are just posting without reward.
This is a very nice post from you and I just gave you one of what we treasure most on steemit. That is me, if I see a good post explaining things like this to newcomers who don't know anything about how these cryptocurrency, forex, blockchain and bitcoins work, I give them a bit of the value we use to encourage ourselves here. Please continue to educate the community more on these I have mentioned. Have a very nice day.
