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.
If you have a growing community all other challenges self-resolve.
I agree with MicroGuy! So it means that you need to do some research/investigation before investing to any coin. Reading the forum or related topic to it will somehow clarify some of your doubts.
