So, I have taken an interest in alt coins as well and I came up with my own set of criteria for how I invest in them. I just wanted to share that with you and would love to hear any thoughts you might have about it as I am interested in refining it as time goes on. I basically put the below questions on a grid with the particular alt-coins I am comparing and I look through to see how they stack up against each other and I make my decisions from there. Here are the questions I ask myself:
1) How has it been improved upon from Bitcoin?
2) Does it have a core group of active developers helping it along?
3) What is the community like?
4) Do I like it (what is my overall feeling about the coin taking into consideration the name, the look of the logo, my overall impression, etc.)?
5) What has its chart done (what does the graph on coinmarketcap.com look like)?
6) Does it look like it has long-term value?
7) Are people actually spending the coin (or giving it away/tipping each other etc....basically...is the coin moving or just standing still in everyone's pocket)?
What is the coin's current price and my perception of its potential to increase in value?
9) What are people saying about the coin in the forums/in articles, etc?
10) How long has the coin been around?
11) What are some of the core ideologies/principles associated with the coin and does that resonate with me?
Hopefully this can be helpful to someone and as I said, would love to hear your thoughts on how this could be refined even more.
Cheers
