I dont think its a stupid thing to hold tight on a million of them, because litecoins were only 0.07USD 12 months ago
You cannot begin to even compare the total number of coins produced between the two. So temper your expectations.
With that said, the biggest draw to Doge is it's consistent daily volume. There are a ton of buyers and sellers, which means there is a ton of interest. Matter of fact, I think it's easily the second highest traded currency out there only to Bitcoin. But again, be realistic in your expectations.
I believe the block rewards is set to cut in half sometime in february, so many speculators are stocking up now in preparation for an anticipated price hike. But with all things investment wise, nothing is a sure bet. Don't know if I would be buying right now at its peak...the volatility of the market shifts from hour to hour...so it could easily drop by 30 percent by tomorrow. I'm personally looking to buy a bit once it has a nice big dip
Actually, believe it or not, Dogecoin has more total trades per day than bitcoin AND litecoin PUT TOGETHER.
I know, it's nuts. Dogecoin's price has been really run up today, but there is definitely something to it.
Hashrate is ridiculous for it though, so I don't know if it's your best choice for mining. If I were you, I'd wait for it to dip then buy in.
