I have been practicing forensics since last 5 years and beg to differ your claims. Lots of information can be extracted from transaction time, amount and associated information. Its all about pattern recognition and hypothesis can be build.

Yes, I am aware that its segwit wallet but I have a question. What is different betwen native segwit wallet and segwit wallet? I have limited knowledge of techology.

I came across a transaction which had 2 input one of BECH32 (P2WPKH) and other was BASE58 (P2SH). Both input transaction combined to send  X amount to BASE58 wallet.

Example: https://www.blockchain.com/btc/tx/d85c24ac2e083d2bc6d453e9b0a1274b94911e73defca7713b283810d4b0e5e6

Is it possible? If so, I assume both have common private key and legacy and segwit wallet was derived from same private key? Look forward to your comment.

I am performing research and practicing blockchain forensics. I am not able to make any sense of following wallet:

https://www.blockchain.com/btc/address/bc1qyq03ld3kmwja8c2sjfvjkw2vg2ma9jq79jp0g9

It has 178 transactions and over all volume of ~500 dollar
All input transactions have following patter:

• Wallets starting with bc1 .... BECH32 (P2WPKH) Wallets
  
• Wallets Starting with 3 .... BASE58 (P2SH)

I wonder following:

1. Is this wallet some donation wallet?
2. Is so who is processing the donation of the wallet as all input transactions have similarity?
3. If not donation wallet, then what kind of wallet it can be as size of each transactions is small?

Any thoughts?
