Invest in Electroneum.

The mass adoption possibilities are what turned me on to Electroneum, I mine roughly 200-300 ETN a day currently, it's certainly hard some short lived surges but for me its the stability of the (albeit low) price that I actually enjoy about the coin. Fluctuations of hundereds or thousands of dollars always get my a little nervous. But moving around 24-80% up or down at 7 cents is certainly not going to sink an investment.
