Well if we do have some fiat I think we should buy the dips. Most of my fiat I did invest in Bitcoin buying the dips and we can do same thing with the alt coins.
For me, I do think we will make more profit if we do invest in Bitcoin. There are not alot of alt coins that I do buy the dip.
Only 1 I do buy now is Ethereum when it does dip down. But if you want to invest in the alt coins now is good time to get cheaper coins.
