Bitcoin of Greece and Spain
Recently, bitcoin has been swiping the screen frequently. One reason is that the story of "making rich" of bitcoin is surprising. The other reason is that the rise and fall of bitcoin is too crazy. After entering 2021, bitcoin is in a rising trend. Although it has declined ring this period, it has always remained at a high level
12 years ago, Nakamoto, a Japanese American, created bitcoin. It is said that Nakamoto himself has never appeared, but the bitcoin he created is crazy.

is it sure to make money by investing so much money in "mining"? The answer may disappoint you again. Bitcoin's "wealth making" is based on the price rise. Once bitcoin's price falls and it is no longer so valuable, investors may lose all of it
some experts have warned that the bitcoin market is the easiest to be manipulated, because bitcoin is mainly concentrated in the hands of some people, and a virtual currency is so expensive that it can not be separated from the hype of these few people. At the same time, there is no sound and mature regulatory mechanism for the bitcoin market in the world, so the risk of investing in bitcoin is great
therefore, for ordinary people, it is better to stay away from bitcoin and "mining", don't you think
second question
the price of bitcoin depends on the buying and selling market - how many people want to buy and how many people want to sell. Prices are going down because we are starting to be able to use bitcoin more and more easily to buy things instead of holding and speculating. The price of bitcoin will continue to decline until an important part of bitcoin economy is closed-loop, so that bitcoin can stay in the loop forever and not go out (converted to legal currency, etc.).
