Either to be honest. I just don't want to put in 100 a month to wake up 1 morning to find rates have massively dropped
If that's going to cause you sadness then you shouldn't put a penny in. It could happen at any moment. People who put money in at the end of 2013 had to wait over three years to break even. There's a lot of risk however you want to look at it. Everyone here's taking it and that's why the rewards are potentially very high or non existent.
