Introduceyourself to my understanding is only supposed to be use once.

Do you remember where you read or heard that? Cause I'm uncertain and I see a lot of other people using it for similar reasons.. Based on my memory I remember that it was okay to use in certain situations like getting an amount of followers, but I admit I can't remember where I originally read or heard that.. I'm not really sure.

And in regards to what you said about steemit and the value.. What do you mean the value comes from the same value as bitcoin? Aren't they separate cryptocurrencies?

I guess I'm a bit unfamiliar with bitcoins history as well, but wouldn't you need a certain amount of money in a bank somewhere in order to pay people who are cashing out? Especially in the beginning like on steemit?
How are people cashing out unless there was an initial investment to make steem worth a certain amount?
And it has to be a decently high amount because some people are making a lot of money on here..
I don't think that can all just come from the value of steem itself, to me I would think there would need to be money to award to people in the beginning and where did that original money come from?
