When comparing to common USA company's networth, all cryptocurrencies's market cap is still resembles small company's st ock networth only. I believe we need at least one trillion market cap to enforce wall street investors to turn their head toward bitcoin or any other cryptocurrency too.
I guess bitcoin is already started attracting common people as a good returning investment opportunity, this way we can expect bitcoin alone to have $500 billion market cap in short term like in net two years.
