Why do the elderly always say not to eat fish tails?

Because the little profit you can make from fish tails is far outweighed by the potential losses from not getting out. The fish tail might only rise by 10%, but it is very likely to be followed by a 50% crash.

The so-called fish tail market these days mostly relies on a rebound or widespread imitation. Last year's example is very typical: starting from December 9th, the imitation market oscillated upward for about a week, but then it continued to decline, going lower and lower; by the 20th, many coins had almost halved in value. A month later, when Trump issued his coin, the small cycle seemed to have come to an end.

I sincerely hope that history does not repeat itself this time.
