Bitcoin is more expensive than it was in 2015. But this does not mean that you cannot make money on it. I found a site where I was able to buy Bitcoin. This is a very good source of passive income. This was proved by Elon Musk, who invested in bitcoins and improved the financial condition of Tesla. If they make money from it, why can't we try to make money? Moreover, there are many financial forecasts and news on the Internet. In addition, if you start investing ready for risks, then everything will be fine. In any case, you will earn.
