I have experimented with many strategies for saving cash. Like saving a certain percentage, say 20% of any income that I get. I have also tried the strategy of saving any coin given as change when shopping in a piggy bank. But a dry financial spell or an emergency always ended up decimating the savings. In the end, I decided that money is better converted into am appreciating asset no matter how small or better, make it work for you not tucked away somewhere.
