a block does not get paid into the pools wallet until 120 confirmations, most pools will not payout before this is reached.
some pools pay earlier, it means the pool operator is taking a risk that the block will go invalid before 120 confirms
Aren't all blocks equal?
How comes my payment inside that block is safe after 6 or so confirmations but the 50 BTC reward inside the same block isn't?
best regards.
