It depends on the developers really. In how they can improve their coins interms of transactions etc. which can be a vital thing in attracting a huge number of consumers. I can say it can be a good investment and a good storage. But the thing is, other coins are also good and can do this too. While others have the same pros, others are more known to people and have better experiences in terms of solving issues. And i think that is something needed to be considered when you really need to invest.
