Maybe the title isn't as obvious as i want it to be, i wanted to know from people already investing in cryptocurrencies how to decide/research which coin is worth the money and which is not, what does it take for a coin to look successfull, strong code? Dev support? Most importantly, how to decide where to invest rather than taking advice on what to invest into.
this question has been asked a thousand times and there is never a proper answer for it because you can never choose only one factor that leads to a success of an altcoin. there are so many different factors all contributing to the success or doom of a crypto currency.
all the things you mentioned are important one way or another.
- it needs a strong code, for example you can't get hacked each month and hard fork and then expect your coin to shine
- developer team is important since they should keep on developing and not just think about making money
- the community as was mentioned is important, but not that much because if the coin is good the community will shape up and people will adopt it. this one is not a thing that can be forced.
