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?
There is no safest way to gain 1% daily profit from trading unless you are a trading genius. The safe bet is to pick some coins that swing back and forth a lot around a certain value. Buy low and sell high. That is it.
what you say is true, the safest way in the trading world does not exist, if someone is already proficient in reading the percentage of ups and downs of the altcoin then he will earn more than 1% profit, but if the newbie might buy altcoin when the price falls and sell when the price high.
