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?
Invest in the top coins, you can invest in that or invest in in Bitcoin while the price is really low.
