because altcoin is an alternative coin other than bitcoin, other than that the price is cheap and can be affordable by anyone. In this cryptoqurrency market there are many altcoins, but not all of them have great potential for future investment.
Really? Then tell me what is your opinion on Ethereum, Litecoin and any other great altcoins out there. They have been alive for like more than a year and still it's a choice for those who wants to invest some of their money to these altcoins. Saying "none of them" is just proving that you are not checking the market anymore
