Relatively large declines last week for the majority of coins, while BTC has traded down just a few percent. There's not really any strong narrative or basket of coins outperforming for more than a few days at a time which makes this a bad environment to actively trade alts unless you're shorting the weak ones. Generally best to chill until you do see some life within a certain sector or group of coins as that's where the gains are generally made. Don't chop yourself up meanwhile with Summer coming up.
