we need to write one to increase our coins I think

Ive tried just creating more accounts to try and pay with separate wallets. that doesn't work. I think you need to gather the public keys from the blockchain page, and do some kind of replay attack on the transactions. hard to say though and completely open to ideas.

You need to make a script to increase your coins, you need an private key and public key. If you contribute some money towards buying VIP on the web application, then you can find your publickey in the blockchain.

I have done all of this but still i am stuck, I have a vip account but I dont seem to find anything to get a footing...

Can you share the script you used to increase the coins?

Sorry to bother you but I'm wondering if I'm going on the right direction with the script:
transaction = Transaction(
    sender_address=vittima,
    receiver_address=public_key,
    amount=10000,
    transaction_inputs="100",
    ids="0"
)

transaction.sign_transaction(private_key)

new_block = Block(
    index=1,
    transactions=[transaction],
    nonce=0,
    previous_hash="09ba9cc6edfd51a0c9b3e7155dcf8dacfcfe23cc0bc7087afd65ab0b0e7d4048acf6d498328cb009996a9066f71de633ed5b123328355d216841581abaad7ece"
)

new_block.current_hash = new_block.get_hash()

url = "http://casino.htb/blockchain"
response = requests.post(url, json=new_block.to_json())
