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

If your goal is engage in trading/investing, I think you have to research first on how trading works because you cannot just invest and trade your capital if you do not know how this thing works. To become a profitable trader you have to know your market first, whether it is bitcoin, alts, stocks you have to gather information before you start a transaction. If it's really your passion to become a trader then make it your way to learn and be a professional trader. If you want to invest, just invest what you can afford to lose.
