We either get motivated or let the envious side of ourselves get activated if we often do this deed using the blockchain to track down a wallet address activities. I must admit, I do this often that the idea of one person able to earn such amount based on their wallet activity will somehow motivate me or let the envy eat me alive and become unproductive at all.
The blockchain and all other forms of public ledger tracks down all transactions from the source of funds to the recipient. It will even show the balance remaining on both ends. You may also track down the origin of all the funds being credited to one wallet to another. You can also see the time-stamp, the fees, and its USD conversion and whatever it is needed for you to find out. You just need to be more resourceful to know the real identity of the person you are tracking down. This can also be a basis that the payment has already been sent or somebody is just fooling you around. The blockchain itself immutable and irreversible. Once a funds transfer was already sent then there is no way to undo the act.
This technological breakthrough has a real lot of use but let's just focus more on the behavior of all the people who are doing this. Sometimes, doing this kind of foolishness seemed to be fun but oftentimes you lose control and become like a stalker if you pushed even further. I will cite some examples where we can peep through the activities of the Whales or just simply try to check on our own BTC wallets thru the blockchain.
Blockchain Explorers
Steemit
Let's check someone's account on Steemit (The leading social media blockchain)
Type the things you see in the URL of your browser and just choose whoever you want to check on by typing the username.

Let's pick my account as an example. You may follow me there as well if you wish. But let's just be objective in this activity and learn.
Then let's see another person's wallet and I will hide his identity but he is also a publish0x active member. When you click the "Wallet Button" it will redirect you to another page but it will prompt you to sign up or log in.

We can also see his activities here if he is sending funds to other persons or where he exchanges his Steem if it's in Bittrex, Bitshares, etc. After knowing that, it's dead end for you. You will no longer have access what he did with his own money. You can also use Steemd for more indepth transactions like how much value did this person gets from each upvoters he had on his posts. Plus a whole lot more activities.
Blockchain
This is really a vague form of explorer. This might not be accurate because of the fees incurred in the transactions but let's just tackle this one for us to learn the basics.
Type in the URL the address you see plus paste the BTC wallet address you need to check.

You will then see the final balance of the person using this address. The total BTC he has received and the number of transactions he has done using this wallet alone. This is not mine. Since 2016 I have 5 major BTC wallet addresses and would make me a multi millionaire if I have just kept all those BTC last December 2017 when BTC reached its all time high. Still the same even until now.
If we scroll down further, we will see the latest transactions this person has done which includes the date, the amount, the sender and the recipient of the funds.
Etherscan for Etherium and ERC-20 Tokens

Yes, this is my own ERC-20 ready etherium wallet ID that I used here on publish0x. You will be able to see later the proof of withdrawals that this awesome blogging site is really paying. Will also be more than grateful to receive tips from you guys whatever tokens you wish to send.
You will see here the actual price of ETH in the market and the rate of change in 24 hours default interval. Check the balance in Etherium, it's actual value (that is for my gas whenever I transfer coins to exchangers). You'll also see where I sent it to, You'll also be aware if there are any tags if the funds are mis-sent, if I scammed somebody, if the funds were stolen. etc. You will also see here the token value that I have. If you will check the red box part. You will see here the BNTY and the HYDRO tokens that I received from publish0x as my earnings from all the blogs I created since March 2019.

These funds are all from publish0x. This site is trusted and proven paying, legit and worth the efforts!
If we click the Hydro button or the Bounty0x this will appear, it will show you the Token details. Let's pick HYDRO.

You will see the Token Name and the Symbol it uses, the actual price in the market and its change rate in 24 hours, and just check the ones highlighted in red. It is self explanatory.
Creeper Banano (Banano Explorer)
Considerably the blockchain of Banano. This will show you my wallet in Banano and you will see the balance that I got. Thanks to Banano for the tip they sent me for being an active member and promoting the program on Twitter. Check their publish0x profile for more info. https://www.publish0x.com/@banano
The latest update is about their privacy wallet which you can hide your transactions here and can never be caught by prying eyes.
The funds that been received here if you will happen to really copy the URL will bring you to all my earnings from their awesome miner.

Not much to see but to let you know that their miner really pays and they really give bounty to whatever they are posting on Twitter.
Blockchair
See the red box and be updated on the wallet addresses they cater.

You can see here all the details you need to know with the one you are stalking. Oops! The one you are checking I mean. Yes this is my Bitcoin Cash (BCH) wallet address that I used to receive and give tips on Memo.cash. It is a Social Blockchain for BCH community. I am so active there and say hello to me if you wish to sign up. Just search fyzeon and say hello or follow me.
There are others like Coinpayments Blockchain Explorer where you can see Potcoin and Namecoin transactions (Definitely not Syscoin since it is a privacy coin)


And then you can see the wealthiest account holders on coinpayments.
Coins.Ph (Philippines)
When you use the apps, then sent funds to a fellow coinsph user then it will be broadcasted to the whole users to see within your network of friends. This is a great way to build trust to the people who you just met on social media for peer to peer payments. It is also indicated there what is the payment for that you really need to fill out when you process a transfer. Your whole identity is at stake here so it is really wise to just only post a legit transfer whether to receive and to send funds.
______________________
These are the things that we can see if we do Whale Watching, and after seeing those figures, let me ask you what do you feel? I hope this will motivate us from doing what is right to earn more with our efforts such as creating awesome posts for us to earn quite a handful.
This can also be a proof of earnings, payments and withdrawals which we can attest whenever we promote an investment site. It should always be backed out by a blockchain proof of transaction.
If we don't want our transactions to be seen by other people then let's check out Spectrecoin (XSPEC) latest post about their Stealth Staking.
We can also try Banano, Monero and PIVX. We also don't give out our main wallet addresses in social media. If we also use Bitcoin.com as a wallet, it provides a lot of wallet addresses that you can use one time and will generate another one after this address has been funded/used. The total balance is definitely hidden from the wandering eyes of the people.
Thank you for reading this far and grateful for all the generous members here on publish0x.
