Your query "how long isk" is unclear, but based on the context of "isk," which commonly refers to the in-game currency in EVE Online, here is relevant information about how long it takes to make ISK in the game:

• Starting with about 100 million ISK, you can begin earning more by engaging in activities like exploration. Using a T1 exploration ship and signal filaments to reach null security space, you can earn around 50 million ISK per hour, potentially up to 100 million ISK per hour in less populated areas. Returning to high-security space to sell loot is part of this process. Using Pochven filaments and equipping nullifiers can help avoid dangers during exploration

• Other income methods include mission running, faction warfare, and lower-tier abyssal sites, which do not require heavy commitment and pay well. For endgame ISK making, activities like incursions, Pochven sites, high-tier abyssal sites, and wormholes are lucrative, especially if you can dedicate about four hours a day to play
