Pocket is up to 695 Genesis claims. There have been several attempts of people wanting to buy and sell tokens; I urge people to take caution in these trades. Make sure you trust the person you're trading with, or use an escrow partner that you both trust. As always, you can see offers by looking for new Pocket posts here.
Security
As designed, Pocket tokens are strictly less secure than STEEM tokens. This is because each Steem account has a couple different permission levels; the two relevant ones are called Posting and Active. When you submit a post or vote, you're using your Posting permissions. When you send STEEM or SBD or start a power down, you're using your Active permissions.

- Trust the people who have Posting permissions on your account. Cryptocurrencies are not supposed to require trust, but you nearly always have to trust someone. Make your trust count.
