In Acts says judas bought a field with the salary of his evil, he threw himself upside down and it was detonated.1-18 ... but in Matthew he says he hanged himself ... someone gives me a little explanation, how did Judas die?

Me do not speak Spanish but this church has a school to learn about jesus

Judas died hanged. What he says in deeds is a metaphor.

In Matthew 27: 5-8 Judas hung up, but with the silver the priests and elders used the blood money for a land "the potter's field" that is a blood field or Akeldama in Acts 1:18. When he fell the head body burst in half and the blood spilled.
