The #altcoin market finally stops moving in sync, that's a good thing.

When #alts rise and fall together - it means the altcoin market is just mimicking bitcoin, with no movement of its own.

When some alts start to rise, others fall, and others stand still - this is the beginning of an altcoin trend. If it happens on the top after rising, that's the beginning of a decline.
If it happens after almost 2 years of a bear market for alts - that's the beginning of a reversal. When the bottom is passed.

At such a moment, choose strong alts, they will grow stronger and more confident (there will be volume).

In a weak market, choose the weakest alts to short - they will fall harder and faster than the rest of the market.
