Don't worry, wall street is watching.
It won't be long before they do more than watch.
How do you know they already aren't in?
But for one, Bitcoin market cap is way too small for Wall Street to get heavily involved in direct Bitcoin investment
And besides, if anyone thinks that Wall Street is going to make Joe public rich by pouring vast sums off cash into Bitcoin, then they are very much mistaken. It is Joe public who will be making Wall Street rich by pouring vast sums into Bitcoin.
