You don't want to miss the train and hold some alts when Bitcoin is moving. Your alts won't just stay stable waiting, they will be destroyed. Most are a scam anyway and don't have anything innovative. Quite a few have some developers that made millions and are more relaxed, trying to build what they promised, but this doesn't mean the price of their coins will keep rising. If these coins are not used for a good reason then their price will have less demand and keep dropping.
