Have you noticed whether all old cryptocurrencies went through ∧ shape in price?
Will all cryptocurrencies have gone thru this and let people make big profit?
Not all. Check CMC, some would just repeat the wave again.
Expect that shapes to shitcoins, OP.
They don't tend to last long for even a single night due to many dumps happening, causing the price to flatten after the whole day of being sold by different types of people who gets them.
