Great advice! You could se that yesterday when BTC spiked just 1000 USD there was some panic in alts. If you have active trades now stop loss is a must in my opinion. Always good to hodl some decent % btc and eth. But also the x10 potential in alts is greater than btc at this point thats why i think diversifying is good. What @Kiimo wrote could see serious gains in btc too but the x 10 and beyound is greater in alts imho.
