We should think simple. The market always has a repetitive cycle and it is our job to choose a good time to buy or sell. When bitcoin increases the alts decrease, that's a kind of case. The second case is that the alts rebound and bitcoin stabilizes or decreases, which is usually case 2.
These are two cases of rotation to make the market become vibrant and volatile. Therefore, I always believe that the alts will come but we need to be alert to choose a good time to buy or sell.
