I do not know, and no one knows. First of all, you need to determine at what stage the market is located, before investing your money. At the moment, I would not risk buying coins, because the market is extremely unstable and can go even lower!
Despite the fact that cryptocurrency market is unstable the coins that worth buying or interest in are coins that does well in the market after the blood bath and market correction but the best time to buy now are during the December holiday.
