Thanks guys for your advice on Altcoins.
Maybe my question didnt cover enough or wasnt specific enough but i can work with almost all the advice you gave me. My main goal is investing/trading.Correct me if im wrong.. but it seems like impossible to predict this market

Damn straight mate, nothing can be predicted with altcoins pricing yet alone bitcoins, it is a game of chance in the crypto sphere.
For instance a coin that you mined might not be added to an Exchange (Or good Exchange) ever, for a very long time or by chances straight away/good tech, then comes the whole part of Buyers and Miners trying to get the best price on each side, TBH it all comes down to emotions when you have money to spend + the news or hope talked about, learn how to play on feelings and you will fit right in
