So I saw an article just now about 2 hours ago, 1st iteration had the coin at .30 then I click another articl and its at .45 then another and .55 and needless to say I just bought a bit at some .75.

What I am here to ask is those who see this at .20 and so on, and this post here only 2 pages long for a coin that is not tradable on Coinbase.

1. Where do they come from out of the blue
2. How/where can I have higher visibility to these types of coins?

I have mined for 3 years now, only broke even and speculated in a lot of alt coins of which most are no longer in operation.  What makes a coin go from unheard of to Coin base material in a day it seems like.  I know that is not the case but what am I doing wrong?  Any feedback welcome and I am no complaining, just curious, where do we find the birth ground for coins that can be Coinbase material.
