Holding is a good choice. I often place this higher than Trading if you are inexperienced. But Holding also needs to have a separate skill to make a profit, have to scrutinize its foundation, use long-term analysis, consider the community around it and events, etc. I personally combine it to make a profit, sometimes I participate in bounty, especially for potential projects, such as Eot (Eon), when ico you can combine skills skills and trading accordingly.
