A friend of mine shared with me his story of investing in BTC. He entered the market at the end of 2019, just in time for the 312 crash in 2020. The U.S. stock market was circuit-breakered five times, and BTC fell to less than $4,000 per coin.
He didn't know much about BTC, so he bought 900 yuan of BTC on 312. This friend is a very conservative person. He is cautiously optimistic about things that he doesn't understand, and he will experiment first.
He invested a few hundred yuan every week until the end of 2020 and 2021. BTC broke through the 2017 high of $19,000 and reached a maximum of $65,000. Then the big drop began, falling below $20,000.
After two years of experimentation, coupled with his continuous learning and understanding, he found it reliable, so he sold his house and invested half of his money. Now this friend is basically free.
In fact, when someone tells you that BTC can make money, if you don't personally participate in it with real money and "trial and error with a small amount", you are unlikely to buy it.
If you participate in it, but don't study, research and think, you are unlikely to continue to buy and hold it for a long time. You can't hold it at all.
Finally, keep an open mind and be curious about new things. Add your own thinking, try and error with a small cost, experience it, and persist, and you will probably gain something.
Experience is a compulsory course for everyone's growth!
But don't play with contracts. You think you are playing, but in fact you are just a gambling dog.
Gambling dogs, gambling dogs, the final outcome is liquidation
