Are you buying high and selling low?

It looks like a lot of people are moving out of alt-coins in to bitcoin.
With such a high price of bitcoin and lower prices of alt-coins is it time sell to pick up more bitcoin?
OR
Should you be taking advantage of a few alt-coin bargains.
Or at least keeping an eye out for some alt-coins when bitcoin starts to pull back?
It's too risky to turn all your money into bitcoin.
Bitcoin is volatile and if you know and understand the risk that you'll be taking it's your choice.
If your money is just staying in the bank and earning very low interest. You may be better to take the risk in bitcoin by buying some when it dip and wait for it to grow.
The profit in bitcoin may grow in lesser time than your expectation. More risk, more profit but invest only what you afford to lose.
