Using a credit card would be an example of digitally stored money. This phrase is used to describe money in its physical form, as opposed to money that is stored away in a bank or digital form. Paying with dollar bills would be an example of using cold, hard cash.
In the past, it was easier for bank notes and checks to be faked or not paid in full. Therefore, people would much rather be paid in cold, hard cash than work based on promises that might be unfulfilled. People could write on paper that they owed money, then escape without having ever paid it.
When miners uncover a block, they get payment in Bitcoin plus transaction fees if that block was used to verify a transaction. The reward for mining is reduced as Bitcoins around the world are mined. They are called miners because they are rewarded for their computational work with newly "mined" Bitcoins. Bitcoin miners are the users who provide their computing power to "solve" the mathematical puzzles needed to keep the network running. Once all the Bitcoin is mined (it is capped at 21 million), new Bitcoins will no longer be produced and the only incentive for miners will be transaction fees. This makes Bitcoin behave like other commodities such as gold in that not only is it a finite resource, it becomes harder and harder to find new "deposits". In other words, it really is a goldmine metaphor. The difficulty of block-mining is also increased as more miners join the network. Reducing rewards and rising difficulty combine to reduce the rate at which Bitcoins are mined over time.

Others want to keep blocks small while relying on slower but more secure full node verification, BNB transforming Bitcoin into a "settlement network". Some want block size to be increased, relying on SPV nodes and allowing more transactions to be handled per block at a faster rate. Those who want a settlement network think that most users on the network should be running full nodes and that we need to limit bandwidth and storage costs, which means there’s no choice but to keep block size small. This means a slower, but theoretically more secure network.

If you send Bitcoins to a friend, your transaction contains yours and Binance your friend’s public keys (shared and stored on the network) and it is signed or authorized with your private key (encrypted and not shared). The high security characteristics of Bitcoin
are achieved through a very clever use of public-key cryptography. This allows the network to automatically authenticate the transaction and verify that your friend is now the owner of the Bitcoins that were transferred. By viewing the public keys of the transaction, anyone in the world can verify that the transaction was indeed authorized with your private key, but they can never access your private key. Public-key cryptography works by assigning two keys to every user: a private, secret key and a public key that is shared with the world.

The nodes that use Simplified Payment Verification (SPV) are called lightweight nodes , which basically lets you validate your own transactions without paying attention to everyone else’s transactions. They don’t verify the entire Blockchain in order to validate your transaction, which means they are faster and btc simpler.
La rete Liquid è stata lanciata nell'ottobre dello scorso anno, e attualmente include soltanto 89 BTC (709.700$). Una cifra irrisoria se comparata a Binance Chain, la sidechain più grande attualmente presente sul mercato, che contiene ben 9.001 BTC (71,74 milioni di dollari).
Since Bitcoin has become so widely popular, the increasing size of its blocks is causing a slowdown in the network. In response, Bitcoin users have adopted one of two viewpoints: This means Bitcoin has begun to fall short of its original goal of being a fast form of peer-to-peer cash.
These channels may form a network of payment service providers (PSPs). In this work we present a protocol for duplex micropayment channels, which guarantees end-to-end security and allow instant transfers, laying the foundation of the PSP network. Payments can be routed between any two users in real time, without any confirmation delay. However, using off-blockchain transactions it is possible to create long-lived channels over which an arbitrary number of transfers can be processed locally between two users, without any burden to the Bitcoin network. Bitcoin
does not scale, because its synchronization mechanism, the blockchain, limits the maximum rate of transactions the network can process.
