I think that in order to choose coins to invest in, you need do provide a lot more information. Almost every coin will have some development within the coming month or two which will supposedly make a big difference.
When choosing which coin to invest in, you should research many many coins and compare all of the variety of factors.
Obviously it's impossible to look at all the factors and all the coins, but the info in this post provides little value IMO. Still, better than just copy-pasting from some news site ;)
