Well, They always say, "Buy low, Sell High!"
What are you buying now?
Of course a lot people say that because it gives you a profit. As of now I buy coins that top 10 in the market . And I think buy low and sell high is proven strategy by all traders.
in top 10 coins I still trust ethereum to be used as a purchase because ethereum has good potential and stable price. so I thought I was waiting for the price ethereum to be in a low position to buy and when the high price I sold it.
