if you think ethereum moves very slowly
you can move it to other coins that you think are potential.
Yes because it will depend on which coins you want to buy, you should have at least more coins for you to choose where to put money. We should always wait for a higher price before we sold it, if ETH moves high this month then take profit and wait for a small correction again.
Its not really advisable to buy more altcoins from your earnings this time because not all some coins are reacting when there is an increase and we see the movements is in unstable, you can notearned quickly by pumping. Better to keep your coins in ethereum onlt for future earnings.
