We should be able to put our ts away somewhere where they grow interest. The longer we keep them where we can't use them, the more they grow. Lets say you make .1t for every 10ts each 24 hours. So if you leave 100ts in for a day, it will now be 101t. Lets say you leave 100ts in for 10 days, you would now have 110ts. If you leave 1000ts locked up for 10 days, you will now have 1100ts. It is solely based on the original amount of ts you put in.
This is a very flawed idea but it would be something to possibly help the T-conomy
