Yes exactly, many alt coins are disguised scams, many big altcoins got down in price like Paycoin, so even if the coin is in the top 5, it can go down.
Bitcoin is the only way to go forward. But if the conflict would stop, that would help btc/
People will use it when they feel use of it and see the possibilities which are more convincing than fiat.Bitcoin is a no go for many merchants,it depends.
I think altcoins are ok, because they have different roles and targed different audiences, but bitcoin is good for everone, so bitcoin gets most of the capital either way.
If you are now looking at the value. You see that the value now is rising slowly and that is very good. People will get some profit later.
