Still, always keep an eye on what people are buying it for. If I see the number of buyers or the price people are starting to sell it for drop off, I would try to sell it because generally as far as I've seen (I'm not an expert economist), a crash has always followed in my experience. It's rising atm but I see a fair amount of tassy buyers. But to answer your question, I think it's a good investment. Just keep an eye on when you sell it. :)
