If you have an address that received 1k coins, and you send it to yourself 4 more times it will show 5k BTC total received. The number of received coins on explorers are not a valid metric.
True, maybe that is definitely how it works. Then why wouldn't it be much larger if these 3 transactions of the address sending 1,200 BTC (

Isn't that like 4,386 BTC sent to itself? And yet the blockchain says "Total Received 3,405.40731067 BTC"? I'm genuinely curious about this because if it counted sent bitcoin to itself, with those 3 huge transactions alone sent to itself, it would be over 4,000 Bitcoin easily. Am I getting something wrong lol. I must be reading this transaction shit wrong and causing undue stress. I'll give up and let the pros handle it

I believe it has something to do with the situation in which all inputs and all outputs are the same address. It shouldn't count that as a metric for 'spent' nor 'received'. Someone else might know the details of this without having to look into it. However, the fact that the 'received' metric on blockchain explorers is useless should be well known.
