Still many rich people not aware of the crypto currencies if they knows then they will get interested on investing on it which make the prices to move further but that is not the growth we wanted we want the people to use it because it can give the freedom of using their money on their own maybe the day not yet come but surely the day will come for that let's hold our hands together and make the bitcoin recognized by common man.
What makes you think rich people are not aware of cryptocurrencies ?
That is not a fact, just some assumption. However, like Hydrogen said, we are still in a system of trade by barter anyway, just that this time around, things are done differently and then we get to have a better way of doing things and transacting as the case may be.
For instance, I can imagine what it would be like when you are paying 12 chickens to someone for a goat, compared to how you can just easily make a transaction in either fiat or cryptocurrency for the goat. Simpler and easier ways of doing things, which is what the technology brings into the whole barter system.
