Just take a look at the charts of Oyster Pearl. Several oppurtunities to make profiting trades. I sold my airdrop almost instantly, few hours laters prices dropped drastically cause of the airdrop. This drop I used to get x10 and keep ETH in my wallet. Later the price raised again, I sold my PRL and right after that it dropped again because of bounty payouts. Another oppurtunity to gain a lot of PRL.

And on top of that, my experience with EtherDelta is that there is a large gap between ask and demand. If you manage to make use of that gap you can gain a lot. I will try come with another blog soon about another project I am gaining x3 in a few hours just by making use of that gap.
