People complain about bitcoin being slow and high transfer fees. To solve all of these problems, lightning network is being developed, but a successful and straightforward solution was not produced, maybe it will never be found.
By using what I have described in this tutorial, you can make a real-time and free of charge crypto money transfer possible. All you have to do is move transactions off-chain.
There is a detailed description of off chain transactions on bitcoin's official information page. As a trusted third party, it is possible to create wallets or payment services that could be worth millions of dollars. I can't believe that people still haven't stepped foot on this. But they are not able to engage in such activity because they do not know BitCoin's infrastructure described in this tutorial. Here is the full link to this tutorial : https://en.bitcoin.it/wiki/Off-Chain_... aiming to explain the basics of crypto money, enabling you to develop services.
When the internet was discovered, everyone had purchased all the valuable domains, with the dream that they would sell them for a lot of money in the future.
Those who held these domains for a very long time, actually made money, but those who really earned money and became billionaires with the discovery of the internet are designers of internet sites and programmers of websites.
When you buy this training and build something using crypto money infrastructure, you'll have achieved a much more valuable thing than keeping crypto money in your hands.
