guys i already checked a lot of places and sites for trends, signals, news etc but I still miss the big picture, which site do you recommend / prefer?
thanks in advance
What big picture you are referring to?
If it's all about website, honestly all your visited is enough as most of them are useful and can be your reference as a starter. Im sure most of them are informative so just keep reading those.
But honestly, just a basic knowledge enough and you don't need to read all of them. As soon as you progress you will automatically learned what things need to be learned.
..is there a crypto you recommend for beginners? I read a lot you should choose one with a lot of up and down moving like tether, or is there a better one?
As far as the general answer is concerned, the mostly answer you will get in terms of long term holding is Bitcoin and ETH that's why it good for beginners since you are in the stage of learning.
Now if you want to step up into advanced learning, you really need to trade another coin on actual for you to see which coins will be part of your trading portfolio. You might experienced loss on the way but it's normal as part of your building process.
