About time!

There is also the speed wallet, USDT (over lightning new feature) or USDT over Ethereum

Let’s break this down in simpler terms:

Bitcoin is evolving, and that change means users will increasingly have to pay for transactions, which isn’t always good news. But we need to face this reality to find solutions.

There are three types of Bitcoin users:

1. Group A: People who can afford any transaction fees without worry.

2. Group B: People who can afford fees but need to be careful with how often they transact.

3. Group C: People who can’t afford to make transactions at all.

In the early days, everyone was in Group A, but now most people are in Group B. The goal is to keep Group B as large as possible. We can do this by:

1. Making the Lightning Network (a way to speed up Bitcoin transactions) more reliable so people don’t need to make on-chain transactions often.

2. Making Bitcoin transactions more efficient so they cost less.

However, even with these improvements, some people (Group C) still won’t be able to afford to make transactions. We don’t have a perfect solution for them yet, but some ideas have been tried:

1. Wait for lower fees: Some hope that if these people wait long enough, fees will drop, but that’s unlikely because many people will be trying to do the same thing.

2. Cover fees for others: Another idea is that a service could cover the fees for people who can’t afford them, but this doesn’t work well because it’s not practical or sustainable.

The remaining options are:

1. Group transactions together: This means combining transactions from multiple people to share the costs, but it requires cooperation and trust within a group.

2. Incentivize honesty: Create systems where a coordinator holds funds for many people, with built-in safeguards to prevent dishonesty. This is complicated and needs more research to make it work reliably.

In summary, dealing with sub-fee amounts in Bitcoin involves trade-offs and challenges, particularly around trust and financial incentives. It’s a complex problem that needs more research and creative solutions, but improving Bitcoin’s capabilities is a key part of the solution.

Central Bank Digital Currencies (CBDCs) are considered digital because they are created and stored electronically. However, they are NOT entirely digital in the way that cryptocurrencies like Bitcoin are. They are simply a type of digital ledger system, meaning they are a centralized database that records and tracks all transactions in the system.

Instead of multiple private banks keeping their own ledgers, a single ledger is maintained by the central bank, and all transactions are recorded on it. Hence, CBDCs are still based on centralized infrastructure, and the transactions are still digitally recorded in a central database controlled by the government.

Therefore, the main difference between CBDCs and traditional bank deposits lies in the underlying technology. While the former is based on shared ledger technology or blockchain, it does not necessarily need to be decentralized. It is, therefore, accurate to say that CBDCs are digital in terms of the way transactions are carried out, but they are not fully decentralized and digital like cryptocurrencies.

I don't know why they call a CBDC "digital", because it is not.
