Last year saw many people predict BTC year-end prices, but nothing was validated with time. it is very difficult for BTC to reach predictable prices. Future price predictions fail to consider many factors and problems that may occur over time. Maybe, we can only estimate the value of assets for the next few days like weather experts.
That's why they called it prediction no assurance to be increase or to drop. Promises is different to prediction because if you say promising it means there's a potential. Like in crypto there's no assurance if you can make a profit that's why it's important to observe everything in crypto.
