hi i have a question about margin pools. whats number is good for that? for example the pool with 5% margin is better than 0.1% margin or am i wrong !!!? would you please some one explain about that
thank you

The margin is what you pay them to run the pool for you. It comes off your rewards. So lower is better, except it’s like other things, sometimes a price is too low so the business goes bust, or maybe it just doesn’t provide a very good service.

You can read about the various parameters to consider while selecting a pool here.
