Because trading is a zero-sum game. The money you keep or lose does not come from central banks, but rather from us individuals. We are the liquidity. And the big players in the market manipulate us as they wish.
I've been saying that for years. The price of the coin is decided by whales. If you are not a whale, you don't know whether the price is going up or down, you are a fish in the ocean where whales soar.
You have to avoid strategies that are popular, because they are the supply and demand, they are the liquidity. And the only purpose of the market is to get out, it is to trap them.
Trading has one simple strategy - buy low sell high. You should always follow this strategy if you want to make a profit but sadly many people buy high and sell low. Btw I always try to read lots of Bitcoin news and be always updated. Being the first to know the news means a lot, it helped me to escape in 2021's Bitcoin market crash. There are types of news that tell you whether the price is going up or down. For example, China announcing the Bitcoin ban caused a huge crash and those who were one of the first to know that, made a good profit. The fact that the SEC was going to approve Bitcoin ETFs was also a signal for people to buy Bitcoins but sadly many waited and now Bitcoin worths 80K instead of 50K.
