A bit off topic, there was a report about how much energy is consumed by the Bitcoin system. It is extremely energy-intensive. It's mainly run on massive computer farms in China, close to coal-fired power plants where electricity is cheap. If Bitcoin were scaled up to replace all the currencies on the flat face of the Earth, it would require more energy than the entire world's current production of energy. Even if it just replaced U.S. dollars, there would not be enough energy. Bitcoin is a niche currency whose value is too unstable to be useful for mainstream commerce, and is mainly useful for black-market transactions where its ability to hide from law enforcement is more important than stability, and as a vehicle for speculation.
I believe that this is propaganda to keep alternative money low value.
In that case, you need to decide if you want to bet that the propaganda will be effective or not. If the propaganda is effective the value stays low and it's a bad bet. If the propaganda fails then the value will rise and you should buy. For the purposes of speculation what you need to do is anticipate the market value, which depends on the opinions of the people buying and selling it.
The value of Bitcoin fluctuates quite a lot. Are you a gambler? If you are and enjoy it, you could buy some Bitcoin. Since there's no way of knowing whether it will go up or down, you probably have a 50-50 chance of making money, and a 50-50 chance of losing money. The same applies to any crypto.
Yes that's true. But it flactuating a lot also makes it possible to earn money with trades.
True again. It makes it possible to make money, and the more it fluctuates the greater the potential profit. But at the same time, it is also possible to lose money, and the more it fluctuates the more money you can lose.
It all depends on whether and how well you can anticipate the market. If you know beforehand when it will rise and when it will fall, you can make gobs of money. But if you guess wrong you can lose gobs of money. We hear about the investments, like Bitcoin, that paid off for the early investors. We never hear about the investments that flopped. And for every big success like Bitcoin, there's a hundred start-ups or concepts that went bust.
I wish you all the best with your investments.
For myself, I don't take risks. I will never be rich, but I have enough to live comfortably. In the words of Hermann the German from Pushkin's short story
The Queen of Spades, "I refuse to risk the necessary in pursuit of the superfluous."
