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.
What do you mean, always wait for a higher price? Are we not supposed to enter any market knowing already what price we will exit at? If you are buying and have no idea of the price you are waiting for, or the timeframe you want, then you should not be trading. For me, it is always a long term picture of price and time,,, and maybe if I come close to my price, I move my stop loss up that is all. Never go in without a target!
