I would have to say to buy some Oyster. It is up a lot today and was at an all time high of 5 USD so it still has room to grow. It is special in that it actually has a working product and use case for it.
Oyster is one of the most certain successes of this year, pearls will grow at least 8X this year, until 8$, the likely market price of cloud hosting 64 Gb . It has already grown quite a lot in December, so I do not think more...
