Now the amount sent is the input

Input is not "the amount sent", it is just a reference to a previous specific output in a specific transaction, combined with the unlocking script that the initiator of the transaction presents as proof of ownership over output. In other words, by creating inputs, you are not moving actual coins but simply expressing your intention to do so.

We're getting into nuance and semantics related to exact technical processes here, but inputs aren't really an expression of intent to "move actual coins". A better description might be to say that inputs are the process by which a transaction indicates the source of the value over which it's assigning new control.

Once you send the transaction, the payment is completed.

The payment is "completed" only if Philip regards unconfirmed transactions as "successful."

This currency is held by your private key which will later be sign by it in case of a new transaction and verified by your Public key.

"The currency" doesn't care at all whether you have a private key to unlock it or not: in either case, it will remain written down in the immutable ledger. Thus, coins always sit inside the blockchain, their existence isn't dependent on your wallet or private key.

Lets assume Bob did a job for Mark and Mark ran out of fiat and opted to pay Bob in BTC which amounted to 0.005BTC so Bob after receiving the coin Bob went to a grocery where Philip sells items of food and he made a purchase worth $50(0.000051BTC) and has the option to pay in BTC so Philip generates a QR Code and specifying how much he needs to receive from Bob in his wallet while Bob scans the code which auto-fill the recipient bitcoin address and the requested payment amount. Once you send the transaction, the payment is completed.

Now the amount sent is the input and Philips receives the output which becomes an input in a later transaction. The balance now becomes an Unspent transaction output(UXTO) which will become a new input if Bob choose to make a new transaction. This currency is held by your private key which will later be sign by it in case of a new transaction and verified by your Public key.

Here is a very insightful, helpful and easy to understand video on youtube from the user "3blue1brown": https://www.youtube.com/watch?v=bBC-nXj3Ng4. I find that video does a great job in detailling the technology behind Bitcoin and how it works so that anyone can understand it, even if they have absolutely no scientific or coding background.

The youtube user in question makes a lot of mathematics/science videos and explains difficult concepts in a very easy to understand kind of way.

I think anyone regardless of their Bitcoin knowledge or seniority, even as an veteran on Bitcointalk, should watch this video at least once in their lives. Even if just to freshen up their own knowledge without having to sit through all the minute details of how blockchain actually works on a mathematical/coders level.

Hi there,

Bitcoin is sent as a transaction on blockchain in blocks.

A transaction has a TXID, we are taking this transaction as an example: https://mempool.space/tx/d23d0b178af6e62771a8d5a4ae81619aa739eeb240654ae58e628e3b885de3dc

Once you open any transaction explorer, you will see the meta-data it includes with itself.

Like at what time, in which block, and how much fees were paid for this transaction to be mined by the miners on the network.

It also includes Inputs & Outputs which describe who is the sender and the receiver.

So in general, it's just a plain text which is stored on the blockchain.

I think Op is not asking how bitcoin works, he already studied how bitcoin works and the cryptographic arithmetics therein. But I doubt he did, because if he is aware of that, he shouldn't have raised the question in Op.

Op is practically asking the form of bitcoin, though he had said that he knows it's not physical, he wants to be able to draw bitcoin when he is asked to. He doesn't want bitcoin logo to represent bitcoin, he wants if it's a code, script, amoeba, maybe a rectangular virus or a blue SVG. I am not Op, but I think I understood the nature of his question.

Briefly, it exists in the form of the digital record which is subjected to the specific protocol.

There's a "rule" in bitcoin code that tells to give the miners the right block rewards. But the coins go to miners' wallet also as transactions. The block reward is just a special transaction and the miner, if he doesn't spend it, will have an UTXO in his wallet.

Note that the coinbase rewards and the fees must both be claimed by the miner (this will become the first transaction of the block). If it does not claim the coins, they are lost forever, and not even private key recovery will reclaim them because they do not have an associated address.

The bitcoins people have in their wallets "exist" as results of transactions (or UTXO, unspent outputs).
This is "the form" you will find.

Aren't those fundamentals enough to know how the bitcoins are stored?

Anyways, it's not in a single server. (you probably know this already)
Every node has/had it's own self-verified copy of the blockchain, which consists of blocks, where transactions are recorded. (you probably know this already)
Stored bitcoins are every transaction's outputs, so coins are just stored as transactions.
Clients/wallet are just making it simple by always checking which ones are still unspent and saving them in easy to access forms.

For the "mined" coins, those are technically called "coinbase transaction" (not Coinbase, the company).
Those are pretty similar to a normal transactions but not pointing to an existing unspent transaction output, also it's the first transaction that's stored in every block.

If read that book you will know the answers for all your questions.
All is perfectly described there, it makes no sense to create own definitions.

If you have studied how bitcoin transactions work, you must have also heard what these transactions do. Transactions in the bitcoin network represent the transfers of ownership over specific chunks of bitcoin called "unspent transaction outputs" or, for short, UTXOs. To transfer the right of ownership, a transaction uses particular UTXOs (created by previous transactions) as inputs and creates new ones as outputs (new UTXOs), which also will be destroyed and recreated in future transactions. A UTXO is a piece of data (plain text) that contains a locking script that put constraints on how and when it can be transferred (spent.) Also, a UTXO, along with a locking script, contains a field with an amount of bitcoin represented in the smallest units - satoshis. It also follows that there are no "bitcoins" in the bitcoin network because everything essentially is measured in satoshi terms.

The blockchain consists of blocks and each block contains one or more transactions and each transaction consists of inputs and outputs.
What we can call "coins" is the outputs in each transaction and they consist of an amount (like 1BTC, 0.0002BTC, etc.) and a locking script which is like a smart contract that defines the conditions that this output can be spent. It usually requires a digital signature from a key that the locking script has the hash of.
