If you haven't done so already, join Bitcointalk. And one strategy which has worked for others is to simply collect "intangible assets". This is the strategy used by Trevon which has been shown to work by the data that all altcoins have gone up over time, at least in the top 10. You just don't want to buy into scams.
Of course you have to settle on your own strategy for this stuff. Craig Grant likes to buy into platforms he can earn on or which give passive income. My own strategy is I like to buy early into platforms which can provide me future utility for what I want to do or which I know are unique assets, well positioned to go up, in other words value driven productive. This is because right now there aren't many intangible assets paying a lot in interest or passive income, if those assets were common and decentralized my strategy would change.
Good luck and if you have success or failures please blog about it so others can learn from it.
