Why they surge
Memecoins are cheap to create, easy to share and move on attention. A viral post or a listing on a big exchange can multiply the price in hours, which attracts traders hoping to catch the next one.
Why most crash
With no revenue or product, the price depends on new buyers arriving. Creators often hold large supplies and sell into rallies, and many launches are outright rug pulls. Most memecoins lose nearly all their value within weeks.
