You say that it was the middle of this 7 year period when Jesus was killed, but then 3.5 years later everything should have been fixed up and finished. Look again at what the prophecy says about the completion of this time:
"Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy."
The end of this 70 weeks marks everlasting righteousness; that is the Kingdom of Heaven of Earth. Is that what happened 3.5 years after Jesus was killed? No way! His followers were hunted, persecuted, and killed. The world is incredibly evil at the moment.
Notice also that in Revelation 10 there is a special angel who, at the sounding of the 7th trumpet, lifts his hand to Heaven and swears that there will be time no more. I believe this is a reference to the completion of the final 7 years of Daniel's prophecy, the one that brings in everlasting righteousness. Compare this with the description of the 7th trumpet from Revelation 11:15,
"And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever."
This sounds a lot like the everlasting righteousness mentioned at the end of the 70th week in Daniel's prophecy.
I believe you are being too literal here. There is a sense in which Christ brought in everlasting righteousness long ago by making eternal life available by way of His death and resurrection. I believe the 70th week is fulfilled. Attributing any part of it to a future Antichrist is a mistake and takes away from what Christ accomplished long ago. Here is my understanding of how Christ fulfilled the 6 things listed in Daniel 9:24 that had to be fulfilled within the 70 weeks.
Fulfillment of Daniel 9:24
1. To Finish Transgression
Isaiah 53 But
he was wounded for our transgressions,
he was bruised for our iniquities: the chastisement of our peace was upon him;
and with his stripes we are healed. 6 All we like sheep have gone astray; we have turned every one to his own way; and
the Lord hath laid on him the iniquity of us all. 7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth. 8 He was taken from prison and from judgment: and who shall declare his generation? for
he was cut off out of the land of the living: for the transgression of my people was he stricken.
Hebrews 9:15 "That is why he is the one who mediates the new covenant between God and people, so that all who are invited can receive the eternal inheritance God has promised them.
For Christ died to set them free from the penalty of the sins they had committed under that first covenant."
John 4:34 "Jesus saith unto them,
My meat is to do the will of him that sent me, and to finish his work."
Romans 4:15 "Because the law worketh wrath
: for where no law is, there is no transgression. Therefore it is of faith, that it might be by grace".
John 19:30 When Jesus therefore had received the vinegar, he said,
It is finished: and he bowed his head, and gave up the ghost.
2. To Put an End to Sin
Romans 8:1 "
There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit."
John 1:29 The next day John seeth Jesus coming unto him, and saith,
Behold the Lamb of God, which taketh away the sin of the world.
1 John 3:5 "And ye know that
He was manifested to take away our sins; and in Him is no sin. Whosoever abideth in Him sinneth not"
2 Cor 5:21 "
For He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him."
1 Peter 2:21 For even hereunto were ye called: because
Christ also suffered for us, leaving us an example, that ye should follow his steps: 22 Who did no sin, neither was guile found in his mouth:23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously: 24
Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
Hebrews 10 10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all. 11 And every priest standeth daily ministering and offering oftentimes
the same sacrifices, which can never take away sins:
12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
3. To Make Reconciliation for Iniquity
Hebrews 2:17 "Wherefore in all things it behoved him to be made like unto his brethren,
that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people."
2 Corin 5:19 "To wit,
that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them"
4. To Bring In Everlasting Righteousness
Matthew 3:15 "And Jesus answering said unto him, Suffer it to be so now: for
thus it becometh us to fulfil all righteousness. Then he suffered him."
Romans 5:21 "That as sin hath reigned unto death,
even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord."
Hebrews 1:8 "But
unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom."
Hebrews 9:11 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; 12 Neither by the blood of goats and calves, but
by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
5. To Seal Up the Vision and Prophecy
Luke 18:31 "Then he took unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and
all things that are written by the prophets concerning the Son of man shall be accomplished."
Luke 24:44 "And he said unto them,
These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me."
Matt 26:56 "But
all this was done, that the scriptures of the prophets might be fulfilled."
6. To Anoint The Most Holy
Acts 10:38 "How
God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him."
Acts 4:27 "For of a truth against
thy holy child Jesus, whom thou hast anointed"
Luke 4:18 "
The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel"
