Dear @crypto.piotr

I believe that value depends on a lot of things like:

Perception

What does a person consider as valuable. For me, I consider bitcoin, steem and other cryptocurrency as valuable in addition to fiat currencies, precious metals and other tradeable stocks.

Situation

Assigning value to an object depends sometimes in a person's condition or situation. If a person is in a desert, he will surely value water over gold, silver or any other things- as its more essential to his survival.

Knowledge/Education

Well, for most of the people and, I am living now in Australia, they still do not know the difference between bitcoin and ethereum here. So basically, one's knowledge of what is valuable depends also on his education and accessed information.

Opportunity

A lot of guys in the stock market are very much familiar with this and well, in lay man's term, asking simply yourself- what is more valuable now- gold, silver, fiat or cryptocurrency. Well, that depends on what the chart in the stock market are saying, right?

To sum it up, if you wanted to convince anyone on considering anything valuable, you get to profile them first so you can determine the most appropriate method to get them on your side.
