<p>My internet bandwidth is around <strong>10 - 20 KB/s</strong>. If I could sync with it for the <strong>first time</strong> then no problem. If I should need to <strong>sync it every time</strong> when opening it then it's really a big problem for me.</p>

Are you sure this is no problem?  By my estimate, syncing the entire block chain will take about 30 days of continuous transfer at that rate.

My internet bandwidth is around **10 - 20 KB/s**. If I could sync with it for the **first time** then no problem. If I should need to **sync it every time** when opening it then it's really a big problem for me.

The initial sync only needs to happen once, launches after a full synchronization will just catch up on the data that you've missed.
