I have only 0.02 BTC and its not enough. 
0.02BTC is low amount but it is better than nothing.. I have saved nothing. but now I am preferring to earn some from bounties etc.0.02 is good to start altcoin trading.. you can start altcoin trading with less amount this is the most nice thing of that. and you can grow your saving..
You are way better than me. I have nothing as of the moment. I always spend the bitcoin I earned almost weekly. I uses it to buy for my everyday needs. But just like you if given a chance I would try to save more. I wanted to earn a little bit more to what I am earning right now. Maybe if I could earn more I will be able to save more.
