Bitcoin price plummets after halving?
Will Bitcoin fall sharply after the halving? Why did meme take off first? Next, seize these three opportunities to get rich!
Over the weekend, BTC completed its fourth halving. During the halving period in previous years, the market was also tepid. It was not until the halving that the long-short game ushered in a decisive battle. The trend in the next two weeks is the key. Pay attention to market fluctuations to avoid being hurt by mistake. A fan asked if there will be a big drop after the halving?
You should know that the cost of the institutions to buy in this time is about 50,000 to 60,000 U. People who know the industry know that the price fluctuations before and after each halving are quite large. After the halving, it will become more and more difficult to mine Bitcoin, because there are not many left, only more than one million are waiting for us to mine. Miners also have to change new equipment to cope with it. After the Hong Kong ETF was passed, big money has not really entered the market. Just like the last time the US ETF was passed, it took a while before it started to rise. This is great news! It is expected that the market will stabilize in May, and from June to September, that is when it will take off, and the price may first rush to the range of 82,000 to 93,000.

PINAX's new 'Block Time' service - evolving from block numbers to calendar dates
Étienne Donneger will show you the 'Block Time' service, which facilitates data retrieval using a specific date instead of a block number.
The service relies on a key-value (KV) store, paired with a substream synchronization tool to pull data from substreams.
Users will benefit from multiple query options, from pinpointing block numbers by date to narrowing down to a specific date range. Simplifying access to historical data, "Block Time" provides customization for different applications.
Explore the GitHub repository to gain deeper insights and make your own block-time based service.

'Block Time' service introduction.
Convert block number to timestamp and vice versa.
Use KV memory for data storage and retrieval.
The role of substream synchronization tools in data population.
gRPC queries are used for data retrieval.
Advantages: Time-specific queries instead of manual block number searches.
Customization potential for various applications.
GitHub repository as a resource for custom development.

Digital asset investment products saw a net outflow of $206 million last week
Last week, digital asset investment products experienced a second straight week of outflows, with net outflows of $206 million. Meanwhile, exchange-traded product (ETP) volume fell slightly to $18 billion. While Bitcoin saw a net outflow of $192 million, few investors saw it as an opportunity to short Bitcoin, with outflows of just $300,000. Blockchain stocks saw outflows for 11 consecutive weeks, totaling $9 million, as investors continued to worry about the impact of the halving on mining companies. #ETP #区块链数据

Trading Rule: Don't Overtrade
Overtrading is the most obvious characteristic of a net losing trader.
Poor performance in one market will affect your performance in other markets. If you can't easily find the reason for your losses in one market, it is likely that you will also suffer losses in other markets.
Learning to stop overtrading requires you to be willing to limit your speculative opportunities and invest more energy in the markets you trade.
The key factor to our long-term success is our ability to manage opportunities and information flow.
One aspect of making the rule of "don't overtrade" work is to focus on seizing the best market opportunities while controlling the size of the information flow and only focusing on key information to help you take advantage of the opportunities you have discovered.
Overtrading is caused by a combination of reasons: not correctly understanding your time frame, not following the trading rules when trading, and not executing the trading system correctly.
You need to set a behavioral bottom line to stop overtrading, and this line needs to be suitable for your trading system and trading plan. For example, the operating method you use requires you to trade once a day.
The unwillingness to control your behavior is the culprit that leads to breaking all rules. #大盘走势 #交易哲学 #交易技巧 #区块链数据
