I first entered crypto world by the altcoin door by investing during ICOs but it's a risky way because a lot of projects are still scams.
If you are able to spend time researching about the project and learning about their prospect ,then you could find good ICO's every now and then and i think it is the best way to make money in this market rather than wasting your time trading with all the coins sitting at an all time high valuations,if your investments are crisp then i think it is much safer than trading .
