Ripple, Stellar Lumens, Dogecoin also. These coins are being pumped very high from time to time. The strategy is just to catch their bottoms and don't be too greedy when the time comes 
the coins you recommend are very good, it's just that we always have to be careful and don't let us miss the opportunity to take advantage when a pump occurs. i have monitored all this time, all the coins that you recommend have a very high pump but they only happen for a short time. like flash pump and flash dump. so we really have to follow every move of the coin.the important thing as you say, don't be too greedy. if it's greedy it won't be good for our wallets.
