These days, it's really hard to use google, isn't it?

There'll be tons of blogs when you search for it in google. There's no all-in-one trading blog. You should combine all of the ideas from one blog to another. To be honest, it's actually easy to do altcoin tradings.
I know there are things to consider like the volume of it and the current market movements, but I think those are just common sense. Experience would be your best teacher, all these blogs can do is give you a heads up of what you'll experience in trading.
