Bitcoin Miner Riot Switches Mining Pool After Falling Short in November

Other payment methods usually ensure miners always get paid, even if the pool doesn’t find a block. However, PPLNS only pays miners after a block has been found by the pool, and then the pool goes back to check for valid shares contributed by each miner before winning a block. The miners then get paid in bitcoin rewards, based on those valid shares contributed by each miner during that time.
