On BTC and ETH daily charts there are clearly seen two wedges  printed. There is a falling wedge on Bitcoin and rising wedge on Ethereum. These patterns tend to break upwards on bull markets. If Bitcoin stops falling in the next days and consolidation phase begins we can see significant growth on altcoins. The perfect scenario would be that Bitcoin goes sideways within the 30-40k range for a couple of months giving the opportunity to the altcoin market for growth. If this scenario works out, every upward movement for Bitcoin within the range will mean new highs for the altcoins, while every downward movement will mean a healthy correction for alts. Again I'm very bullish on alts at the moment, just compare the two images!
