Is bitcoin investors more focus than altcoin investors?

[cryptjh]

To buy most altcoins you need to hold bitcoins, so it's not easy just to have altcoins. I think most altcoin investors who just hold altcoins on exchanges, will sell there altcoins if they can see profit in there trades.
I think most bitcoins holders who are active traders also trade altcoins, the really big swing trades are done in altcoins.
