yep because they are following bitcoin trend. i think it's normal for the current market situation
Bitcoin did not lose so much as many altcoins managed to do. I feel very sorry when I see how my favorites are falling. I hope, they will recover in less than 2 months.
This is natural while many people complain about the volatility of bitcoin they do not stop to think the volatility of alts is even greater, this is why alts can grow faster than bitcoin when the market is bullish but now that the market is bearish even some of the best altcoins have go down faster than bitcoin, so for the time being it seems the best we can do to protect ourselves from losing even more money is to put our money in bitcoin.
