You need the wallet and to make sure thats upto date.  Store your BLK in that wallet and it will stake after some time of being live and available on the network.   Post a screenshot of the wallet and we'll have a better idea of if you are in the right place, see the OP

I'd be interested to mine on that pool, give it a chance and see where it goes.  If only to test a new card and get back into the scene a little and setups required and end up paid in a coin I want, that could be ideal.

Does seem a very optimistic atmosphere at present, Ive read articles on various blockchains and their potential in national newspapers and news of Japan, etc.   I see some big changes in various prices hopefully it can be of substance
