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?
Thats the problem with cryptocurrency and trading them, you can't really control your profit because the market is so unpredictibale and it could change at any given moment so your profit is not always 100% sure from it and espacially daily profit, but the best thing you can do is invest in multiple altcoins that are very promising and are bound to go up, and probably you might be able to get some daily profit from them.
