I think bitcoin is the king, so holding altcoins (even ethereum) is high-risk method right now, if bitcoin hits 25-30K many altcoins will drop 100% at latest, so trading is the safest way for me!
in your opinion what is the safest way to gain 1% daily profit from trading?
Trading is not that simple and easy way to make money, even only 1% daily. Most people use trading not to make profit but to grow up their fund ( asset ) and replace it at investment way. How about make profit 1% a month? it's more easy and will give you more time to understand real market and fix strategy. If 1% is not good number you can raise your fund for bigger margin to get more profit. Just like that and thank you.
