I'm pretty new as well... I'm trying to get a lay of the land still. But this is my list of things to do so far:
Buy coins and hold them (long term investing)
Buy coins and spend them (to buy products, services, or other coins... the whole idea is to spend them, right?)
Do more short term trading between currencies to make money (short term trading)
Buy alt coins and hope they go up
Look for ICOs and buy tokens if you think its a good investment
anyone want to add to or amend this list?
