I wouldn't even put money into any altcoin unless it's been around for at least a month while able to hold a value. Before then you're better off mining it. Even with an old laptop I'm able to get a few hundred of these altcoins the first few days they come out. Also you have to realize that in the long run a majority of these altcoins will be dead or near worthless if they haven't been able to prove their worth and importance, so like all coin trading, sell at peaks and buy back at dips. I wouldn't hold on to any of these unless you only spent a few hours mining thousands of them and don't care (like our doge friend).
