So, having said that, does anybody know how to transfer ETH anonymously?...maybe someone could suggest a program, platform that could allow that?
Is ethereum having full node wallet? You can make use of the full node wallet.
Or if you are using SPV wallet, you will need to make use of coin control appropriately. Use Tor anytime to you want to use your wallet, change your relay circute if connecting to another wallet. Access each wallet with different Tor relay circuits so the wallets are not connected together by the central server.
Generally not using IP addresses for any connection related to your wallet.
I don't think just using full node will simply make the transaction anonymous/pseudonymous. There is a lot of factors that still need to be considered.
There is no such thing as an SPV wallet in Ethereum. Probably what you mean is a light client. And AFAIK it is nonsense to make use of coin control, it's completely invalid. Ethereum is not based on the UTXO model but rather account-based, so again, there is no such thing as coin control.
You seem to compare it to Bitcoin, in fact, both ETH and BTC is completely different.
@OP, as other suggest, if you want to seek privacy on ETH, you should learn in-depth about Tornado Cash.
