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 life of any coin is the community,if the coin is not gaining any support from miners.holders and traders it will just sunk,so far the coins worth investing are those coins in the top ten of coinmarketcap,they have build their reputation,their volume and traders and miners continuously support the market they are in.
