As we know, the beginning of the crypto world started with Bitcoin. This currency was launched in 2009 according to some of my research. However, no information was given about the person or group that released it. For this reason, I would like to state that it is not safe to invest in this currency. This currency suddenly took off in 2019. This currency, which had the highest value at the beginning of this year, has recently suffered a great loss of value. I think that this project, which has its own blockchain, is one of the fastest. As a result, transfers of this currency are very fast. Despite this, I can say that I do not prefer this because the transaction fees are high and its value changes per second. Currently, very few people in the world do not know about this project. In general, although this project is the foundation of the crypto world, you should remember that when you invest in it, there is a possibility of sudden collapse and you cannot hold anyone responsible for it. However, since this is the most popular, I think many users like it.
