I've been closely monitoring both the BTC chart and the market cap of altcoins (excluding ETH).
The current support level for altcoins is quite strong (Fib 0.618 on daily and weekly support). This support needs to hold if we want to see a recovery in the altcoin market or at least a stop to the ongoing decline.
