One of them is in this forum. There are many places if you really want to find accurate information about bitcoin development and many friends before me have provided links to places for you to learn. However, since you are already in this forum, make this forum your main information to learn bitcoin in detail. Because this forum is the oldest forum that discusses bitcoin and there is a lot of accurate information here, you can search for topics that you want to learn more about. One more thing, most likely only in this forum that does not provide fake news.

In this forum too, if you are really serious about studying this forum, you can also get bitcoin by joining the signature campaign, this is one way to get bitcoin. But if you want to get bitcoin in another way, you can buy it on the exchange.
