Reward for making an intention to give sadaqah multiple times during the day

Q: Through out the day I keep on making intention that I will give one pence of sadqah and keep the record of how many times I've said it on my notes in my phone. At the end of the day I've recorded that I've made intention of giving sadqah of 1 pence 98 times and then at the end of the day I give £0.98 in sadaqah just once.

I just want to know, do I get separate reward 98 times for making intention and writing it down as sadqah or do I get only one reward when I donate that 98 pence together at the end of the day? Is this bidah

Wasting food and helping people

Q:

1. Is it permissible to throw +/- 10 tons of wheat and rice in the middle of the sea from a boat as food for sea creatures, even though we know that a vast majority of humans are hungry. What does Islām say?

2. I heared a Hadith saying that a person has to fulfill the needs of other persons,

My question is that, how to avoid and discourage people from asking or does one have to fulfill their requirements?
