Many buy bitcoins and altcoins, they wait when the price will rise and sell. What other ways do you know?
Many people buy at dips and sell when price surges because it is one basic principle that works for cryptocurrency investment. Anyway, you can consider other cryptocurrency investment platforms which give percentage interest if you save your coin with them.
This time people are in demand to buy more and more tokens from promising coins. Yesterday a lot of people have made 10x from TOP network and that's an awesome thing that i was seeing in this year and it looks like the traders are moving toward the ICO investment again.
