Hi Hodlers

I have 2 questions but first my hashrate with I3 7100 is around 180h/s using -t 2 (two treads only).
Two questions, besides the oficial miner in the wallet, i found two other miners:
the one listed in the pool:
http://hodl.optiminer.pl/and this one "hodlminer-optiminer-fork"
http://cryptomining-blog.com/8196-new-faster-hodlminer-and-a-new-mining-pool-for-it-now-available/The sizes are different, but when I use the comand -V, to see the version they acuse the same version.
Which one is the most recent?
And the second question, what I´m mining NOW in the pool hodl.optiminer.pl, will be transfered to my wallet adress only after 1 year right?
In the meantime the coins stay in the pool?
thanks guys!
