Price out of their reach? What you mean by that. No one force them to buy whole bitcoin. They can invest as much as they want buying fraction of bitcoin.
I was thinking that most people would still choose to have 1 shitcoin worth $500 rather than 0.01 BTC, it's just a matter of numbers. When I talk to people about it, they mostly think that way - because they think they get a very small percentage of something for the money they invest. No one disputes the fact that everyone can buy maybe $10 worth of BTC, the thing is that many are looking for cheaper alternatives that may bring them big profits in the future, because at the end of the day for most it all comes down to profit.
