Has Grindelwald Made a Horcrux?

In the first instalment of the 'Fantastic Beasts' series, Fantastic Beasts and Where to Find Them, there is a lot of tension amongst the magical population, as Gellert Grindelwald gains power. At the end of the movie, it is revealed that MACUSA president, Seraphina Picquery's right-hand-man is Grindelwald himself, disguised as powerful Auror, Percival Graves.

As Picquery orders her Aurors to take Grindelwald away, he mutters to Newt Scamander, "will we die, just a little?"

This statement could be interpreted in many different ways, with a possible hint at a horcrux.

In case you are not aware, a horcrux is a magical object that houses a part of somebody's soul by an act of murder, meaning if someone or something tried to kill them they would stay alive. In order for that person to be killed, the horcrux would have to be destroyed. Lord Voldemort, on his quest for immortality, created 7 horcruxes, and by doing this he stayed alive even when his own killing curse rebounded upon him. A notable side-effect of encasing a part of your soul in an object is how the process alters your appearance. This possibly could explain Grindelwald's changed appearance from a handsome young man to that crazy middle-aged man above.

In Fantastic Beasts and Where to Find Them, Grindelwald gives Credence a Deathly Hallows necklace, saying if it was touched he would go to Credence. I think that this necklace possibly housed a part of Grindelwald's soul, and when it was touched he could feel it. It is said that Voldemort could not tell if one of his horcruxes were destroyed, however there is no saying that if he created less than 7 he could feel it being destroyed, even touched. It can be noted that after Credence becomes in contact with the necklace he seems to have less control and become more violent; an influence we know horcruxes can have on people.

Furthermore, I believe that when the Aurors attacked Credence, it does appear he died, although a wisp of obscurius-ey stuff can be seen floating away. We do not know what range of spells destroy a horcrux, so it could be that the spells that were used on Credence had no effect on the necklace. As we know Credence returns in the next films, with the wisp hinting he is still alive, and a cut scene showing Credence boarding a ship. I believe that he survived with the help of him holding onto the horcrux for support, and then escaping. It is possibility that in future films, that part of Grindelwald could kind of mould inside Credence, with Grindelwald using the combined power of obscurus and horcrux to become more powerful.

Now turning to Grindelwald's capture. As we know there is an execution room in MACUSA, so I believe first Grindelwald would be interrogated for answers of his crimes, and then he would immediately be sentenced to death. This could be a way to show us scenes of his time with Dumbledore, adding a further backstory, where he was genuinely happy. Then it would appear that Grindelwald would be dead, and there would be a time of peace, until 1928, when the next movie is set. People would be happy again, and we may see Jacob have expanded his bakeries to Paris, and Newt coincidently being there to study magical creatures. Then, with the help of his horcrux, Grindelwald would resurrect.

In a spoiler on IMDB, there was information (now deleted) that Dumbledore set Leta Lestrange on a task to find Newt to try and help Dumbledore defeat Grindelwald. I believe Dumbledore being aware of his old friend's rebirth, he came to understand horcruxes, backing up the knowledge he gave to Harry in the Harry Potter series.

Finally, in 1945, we know Dumbledore ended Grindelwald's terror in a ferocious duel, which resulted in Dumbledore beating Grindelwald. It is a possibly that the Elder Wand, which was in possession of Grindelwald, recognised that he was incapable of accepting death, following his creation of a horcrux/possibly horcruxes, and passed the allegiance over to Dumbledore. Somehow, his horcrux would be destroyed, and Grindelwald would regret his actions, leading him to welcome death, after the severe guilt he felt of his terrible actions in the wizarding world.

I know this is all a bit of a far-fetched theory but it's just an idea.
