Good point, some people don't want to waste time trading.

In purpose of getting altcoins, you can always use the app to get a cheaper price, buy altcoin, wait until it grows higher and then sell just enough to get your money back and rest of altcoin stays in your pocket as profit and you can wait few months till it worth 600% more.

This way your 5% profit from single trade could become 30% or more with time.
