Hi I created this post so that people can share ideas and ways to advance yourself with cryptocurrency other than just buying and selling on exchanges. So this could be things like masternodes for example as an investment opportunity. But I know there are tons of other way to advance yourself in crypto. Let's try to exclude bounty's and campaigns for the most part and stick with ideas of what you can do right now as far as using crypto to create investment growth. This could be easy airdrop opportunities, proof of stake, holding coins that will give certain advantages/ privileges in the future...share your knowledge.
You would still need to invest or buy coins when we do talk about masternodes if you do plan to have passive income.Ive seen some coins in the market but sooner or later they aren't already profitable and ended up on losing coin holders confidence when they dont already make such profit for a passive period of time. Gaining money would just only by other terms which you had mentioned which is excluded on your list.
