Being a bad sign for altcoin, when dominance of Bitcoin goes up like this will make altcoin fall into bear market for a long time.
Almost all the altcoins are losing against bitcoin when I checked at poloniex this morning and bitcoin dominant is increasing since the current bull trend commenced in April. I think before the end of this August we would be talking of 70% and that is going to kill the altcoin market further. There are some altcoins that I hold that have lost over 80% against bitcoin since this bull run started and some of them has even lost 95%. The current bullish trend is about Bitcoin and not other coins and that is a sign that Bitcoin has started getting trust from the General public and people are looking at other coins as shitcoin
