, to get the most of a small amount of money, its definitely advantageous to take part in the daily/weekly challenges.
An example of the daily challenges is play in one SnG, play in one BIG Trny, Play one Spin-n-Go, etc., etc. Some have requirements of playing more than one, or having to cash in a specific trny. Also, the Cardhunt challenges, and now the new MTT Schedule Quest. When you complete these requirements (depending on the challenge/quest), you are given cash, a ticket that you can use in PS Freeroll Trnys of your choice, or entries into bigger trnys like an upcoming 50k Trny.
You can make a small amount go a long way with a little luck. Not just for the possibility for winning, but for also accumulating Starscoin.
