Investment requires a return, a return means a raise in price, a raise in price means high market demand, high market demand means adoption, adoption requires services, services need an audience, audience needs utility, and utility means useful use cases.
What you’ve identified is one use case: A method for acquiring the currency. But without a way to spend that currency, this provides no utility, so there’s no audience for it, and since the coin’s direction has caused the price to get into a race to the bottom, no one is interested in spending it, so no one is incentivized to accept it as currency.
The time to do this was the second half of 2013, when the coin had the interest of the market. Without a change to the inflation model, you cannot use this as an investment vehicle in the traditional ‘buy and hold’ sense because the economics have been continually retarded by it’s curators and it’s now in a state of hyper-inflation and massive centralization with no security. It’s literally the worst case scenario economically speaking.
What remains solid is the technology. It has performed exactly as it was designed to. That should come as no surprise: It’s the same code that runs Bitcoin, just rebranded and tweaked slightly.
