What makes it strange is usually the actual coin price, different from the price specified at the time of the broadcast message.. for example, when the signal is broadcast, the price of ABC coin is $1, but when checking the market, many cases find that the price has changed by 3% to 5%... this greatly affects our profits later, and we also feel doubtful because we think the signal is still valid or is it no longer valid?
For signals that provide a time span, it may provide a slightly better picture... but for signals that only provide a message to buy at a certain price, and its selling target.. that information is really not friendly to novice investors.
There are times when we can follow what the signal provider suggests, because we may not have time to do the analysis.. but my advice is, don't be too dependent on the signal provider... because you will be manipulated if you are too dependent.
