As far as I can see, in order to invest in this market you need to understand its nature before investing. This will give you confidence and perseverance when the market goes down.
Whenever you think that I have to invest somewhere then chooses the modern market which will payoff the most in case if you invest here. Cryptocurrencies are valuable in which some are more valuable while some are less valuable.
If you are investing in the Bitcoin which is more valuable then you will get huge profit from it. On the other if you like to invest for short term then the best option in front of you is the Altcoin and may be Litecoin because these are less valuable.
