Not all altcoin is useless because in fact there are some good coin nowadays despite of this current because of being have a strong structure behind. Which is it's up to you how to choose good project because only scam project nowadays is useless and turn into shitcoin always.
I agree. Although it can be said that altcoins can't compare to Bitcoin in terms of value and in terms of popularity, there are many altcoins around the market that are still performing and are showing good trends. One good example of those coins is Ethereum. Although it has fallen from grace in the past few months, it's beginning to show good movements climbing up to 250 dollars at the moment. There are many altcoins that directly run with Bitcoin during its gains, and that gives people a good investment asset that, unlike investing in Bitcoin, would not break the bank. It's just a matter of choosing what altcoin to use because there are still good and promising ones out in the market.
