Infinitecoin (IFC)
Great community and a lot of new projects in the pipeline. One of the highest ROI coin in the past month. Great Investment.
Litecoin (LTC)
Looks still undervalued. Always rises more than Bitcoin. When bitcoin rose to 1200$ (6x returns from 200$), litecoin rose to about 40$ (20x returns from 2$)
Bitcoin (BTC)
This is still by far the most accepted coin. "Safest bet"
Other than these 3 I dont think jokes like dogs and cats and moons will go anywhere in the long run!
