It seems to drop as low as $15 before jumping back up to $17-$18. Sit and wait, watch it like a hawk, if it drops below $16 start buying some more.
Have patience, learn about what you can do to spread the word of Litecoin.
Start asking companies if you can pay in Litecoin, and if they say no, don't buy anything, tell them when they accept LTC you will make purchases. Then follow through.
Tell ALL your friends and family to buy Litecoins. The more people you get involved, the more likely the value of your coins will go up!! You can do something about your situation.
Instead of worrying, do something positive, you will fell better and help yourself too.
