Concerning AI subscription fees, the writer has something to say. The most ideal method is to use two platforms, one free of charge and another need to pay monthly fee. Thus your cost can be lowered and also can get views from other venue. The writer always quote data from Microsoft Copilot AI, not because it is the best, but because it is free of charge. So readers can continue to ask it for elaboration on a free of charge basis. Actually, nothing on earth is perfect, no matter what version or what platform you are using, there are still some blind points and will be talked about tomorrow. When using AI, should mind the blind points first.
Anyway, using AI is to broaden your horizon, so it is not so suitable to use just one platform, and should use at least two platforms especially in the financial market. The trading actually is a zero sum game, when you look good on a stock and want to buy, there must be someone look bad and want to sell, or else the trading cannot be done. Actually, buyers and sellers are having different views points at the same time. So you must look broader and ask opinions from more AI platforms.
As for subscription fee, there is a very interesting symptom. For example, if the monthly fee is $20, when you pay an annual fee of one year, you can get a discount. But sometimes your will find that something very attractive, when you pay just $50, you can get a lifelong subscription, not just one year, but lifelong. Why so attractive? Mind that it may be an old version already replaced by new version. So please check carefully whether it is version 2.0, 3.0, 4.0 or 5.0. Some people may say, even the old version is better than the free of charge version, if you feel so, then go ahead, Just make sure there is no misunderstanding and you are buying what you want to buy. Anyway, when prepaying the future monthly fee, it is not advice to be so long, at most one year is enough, for before the end of one year, surely another new version will come out, either by this platform or that platform.
