Help/Support [HELP] What instruction can be hacked ?

[TheArmKing 60.4k Xiaomi A1 9.0.0 Pie]

Hello , 

I was trying IDA recently , and i searched for coins and i got this function : 

 

The function is a void so can it be hacked ? and if so its definitely a LDR right ? as LDR loads the value into it ... 

I think the Second LDR :

LDR R5, [R0, #0x38] 

should it be changed to

MOV R0, R7 

DO i need to BX LR it as well ?

Thanks

I suggest you to breakpoint so you can find out which Register holds the coin value
