In my opinion, the best way for you is to spend money on advertising, Tcredit or the standing order. It all depends on how much you are able to spend.
If you have less than, let's say, $50, you should focus on advertising to get more members who will get you more money and To stay EA2 unless you are BTL.
If you have more than $50, you can buy Standing order each month and go for BTL and even more like buy PSAs, Co-Ops, paid advertising and so on.
