Acquired some ETH, need some guidance.

Last week I acquired a decent amount of ETH tokens. I am 21 and don't really need that much cash right now so I am thinking of keeping it invested in ETH(plus I am a staunch advocate for decentralized currencies, so I'd honestly rather keep it on the blockchain, plus taxes so…). Need some advice on how do I track the latest news and prices and want some advice around ETH in general. What are some things I should be aware and concerned about? What are your opinions, is it a safe investment for the next five to ten years?
