The cryptocurrency market is presently in a correction stage, correcting its prices because of the massive bull run that happened late 2017 and the correction period is always longer than the increase period. Veteran's in the market understand this very well and are focused on buying the bottoms but the newbies are the ones complaining and nagging about the market prices.
Of course when the correction in the market is the right time to take those coins that you like and that can bring you good big money ! and if you look at the market now it is suitable for investment !
