if I have a wallet with 100$ and I sent out about 90ish transactions from said wallet, could someone check the ledger and identify said transactions came from the same source?
The traceability of the blockchain can publicly record every transaction.
Blockchain.com and BitcoinWhosWho.com are mainly used by two tool websites. The former can be used to browse blockchain records, and the latter can provide detailed information about Bitcoin wallet addresses, and can also be used as a public database to help visitors inquire about addresses related to fraud.
