It seems to me that screenshot is a fake and that guy is a troll.

This has got scam written all over it. Why would you store 100 BTC without a password written down or something you'd definitely remember.

Sounds suspicious but its perfect topic for me, already helped poor folk before that lost ~28 BTC. He gave me 2 BTC for it so i was also happy

Yeah if you look close enough you even see that +50 BTC transaction was edited. It is much clearer than the numbers above, which have the JPEG compression artifacts all over them. You can even see how the original number was painted over using a circular stamp tool that copied some of the grey background.

Besides that I can guarantee that for a normally used wallet having 100 BTC flat with NO change is pretty much impossible. Especially since there were no flat transactions.

as i said before it very strange if the balance can get the right value without commas,

But what would the motivation be, to do that? Attention seeker? or just troll?

I will never store, that amount of coins on any platform on the internet. It could be Paris Hilton or Bill Gates under a pseudo name, but they wipe their ass with that kind of money. 

Eish, what would people do next. If it's a scam, I am too dumb to figure it out.

He is also claiming that he has lost dogecoin wallet password and offering to sell it for 3 btc so..

I dont get the basic fact that why someone will keep 100 BTC in a wallet relying on password. Anyone having this volume must have the private key of the address/addresses where this wealth is spread. Looking at the post, how he wants to sell it by luring at 100 BTC, it is quite evident that it is a SCAM attempt.

selling nothing for 3 BTC seems suspicious also

no one keep 100 btc in a core wallet without a backup .. well i cannot store more than 0.1 without backup and you .. 100 btc oh man.. shit.
