Well, for the sake of discussion, lets suppose someone sends you 10 bitcoins
BTC by mistake. Now will you return them back ?
Morally, yes you should return them back but seeing this big money, greediness also can influence our decision.
So, everyone tells with honesty, if this ever happens in your life, what will you do ? Will you return them or will you change your fortune
I will return the question to you, Sir, if you were the one who sent 10btc unexpectedly, would you return it? doesn't it seem very tempting because the value of 10btc is too big compared to its current value of more than 170k$ plus.
But they say there are only two types of people, good and bad. If we are the kind of people who hate doing bad things and believe in karma, there is no doubt that we will return it, but if we are the kind of people who are wild and greedy for money, of course, we will not return it first. Now, if you are the type of person who is in the middle class, you can think twice, because you can think that this is God's answer to what you are praying for, and you can also say that it is not your fault, and because of that We may not notice that greed has entered our thoughts, but in general if you have a good heart, you will give back to the person who sent you.
This situation, we don't know, maybe God testing and measuring the good character that we have. Because if we do good we will reap good and if we sow bad we will also reap bad results.
