Ramadhaan & Fasting

Kaffarah for fasting

Q: Can you please clarify the following. If some one did not fast at all in ramdhan without any valid reason, do they have to give kaffara for all the fasts, which would be 60x30(1800 rozas), which means they have to fast continuesly for at least 5 years? If they did that for five Ramdhans that means they have to fast for at least 25 years nonstop. How is it possible for anyone to be able to do that or even feed that many poor people? I am asking this because in my teenage years, after becoming baligh, I did not fast. I am very ashamed of that and I am now doing all the qazas of those years and I have nearly completed all my fasts. But I'm very worried about the kaffara, because I know I will never be able to fast nonstop for 25 years nor will I be able to feed so many poor people. I will however, be able to give 1.5kg wheat for each fast or equal amount of money. So is it possible for me to do that? Please give clear answer.

Questions related to Qadha and Kaffaara for fasting

Q: Are the rules same for intentionally breaking a fast in Ramdhan, and not keeping a fast at all for no valid reason? Under what circumstances do we have to do kaffara and under what circumstances do we have to do just qadha? Does breaking a fast just because you were hungry or you felt you don't want to fast anymore need qadha and kaffara or just qadha? Does not fasting at all need kaffara as well as qadha or just qadha?
