so many people are just buying altcoins and erc-20 tokens without even considering how they can be used in everyday life. whats the worth in buying a token or coin and you cant even spend it in the real world because its not accepted as a means of payment. if has no everyday use its not valuable. the main generally accepted coin is bitcoin so to me this is the only coin with value. yes there are a few others, such as LTC,ETH,XEM however bitcoin is the main.
