VTC Block 838556 12% 50.043 Effort 1% Explain please..

Oh my shares are 12068   VTC: VgrrxBQxXKbnKkLWRS9vbcn1cYf9yr3FPv

Also what does 12% status mean?

Effort is the combined effort of all miners. Not yours alone.

So I'm trying to understand this. What is the point of waiting around for a block to be found? Couldn't someone just join our pool and mine that block and then leave until the next one? What's the purpose of mining our time until a block is found do we get paid more or?

Okay reading some more I see it's a build up of shares and you contribute to that block and get paid for your work. Hence why sometimes it takes a while to find one because we're searching for I think?

If you're mining alone (not using a pool, or nicehash or whatever), you only get the reward (the coin you're mining) once a block is found and validated, which can take days, weeks, months or years depending on the difficulty - but you get all of the reward - e.g. VTC is currently 50VTC (worth about ~$430 currently), and you'd get to keep that all to yourself.  However, for most people solo mining would take a very long time to get a reward.

Huge pools like what nicehash was, were finding blocks very quickly, which meant even small contributors were getting a trickle of funds throughout their time, so they would see the fruits of their labour pretty quickly.

Smaller pools (like this one), generally take a lot longer to find blocks, and can be a bit erratic.  Once a block is found and validated the reward is spread among those who contributed to finding the block.
