What are the reasons my DTV visa application was canceled, and how can I improve my chances for reapplication?

Hi there, I applied for DTV (Workcation) at Delhi Consulate on 28 May and got 'Application Cancelled. Disqualified'.

Here is the overview of the info and documents I submitted:

1. Have visited Thailand before: Yes (but this was from my old passport and I got renewed passport just few days before applying DTV)

2. Proof of current address: Arrival stamp in India from 15 days before applying the visa (but this was from old passport) yet nothing about old passport I mentioned in the application.

3. Proof Of Remote Work: Provided my NZ and India Company Extract initially. Was requested Employment contract 5 days after I applied, which I created and signed and stamped myself with all details regarding remote work, salary/dividend etc.

4. Proof of funds: Deposited 16k USD worth of BTC into Xapo Bank, converted to USD 1 day before applying the visa and sent the USD statement. Also there were multiple transaction of 2k-3k USD in and out every day from last 3 months. Also added Revolut NZD statement for 3 months which had not much balance but numerous transactions of 2k-3k USD and also many card transactions in Thailand.

5. Was also asked more documents for current address proof, for which I sent my Indian driver license and National ID (Adhaar).

3 days after submitting the additional documents, I got the email 'Application Cancelled. Disqualified'.

Now I am planning to apply again but don't want to make any mistakes. I am currently in Thailand 60 day visa free and planning to transfer my BTC again to Xapo bank again but this time keep for 3 months after converting to USD. But I am not sure that the bank statement may have caused the application cancellation last time. Could it be passport arrival stamp before the even the passport was issued? Could it be the self attested employment certificate?

What are your guesses and advice?

Would really appreciate any response! Thank you
