If you have the funds to spare, I don't see why not buying some; personally it does seem like a good investment (of course that is just my speculation as well). If I had the funds personally, I'd consider buying a few dollars in bits, I'd also invest into the newer stuff too while they are cheap (since who knows what's going to go up in a few years time).
Again, just my opinion. I am a semi-newcomer who's trying to jump back on the train (so to speak).
