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.
The heart of any cryptocurrency can be found in the spirit of its community. Therefore, look carefully at the community.
That's true the community has a big impact in the development and adoptions of any coin,even if the coin has a good features but if there are no community support I don't think it will go farther,the holders or the community should be actively participating on it.
