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?
Obviously you are looking at the 2017 bull run of the coins .most of the coins that time were super high and then came down a lot . You can't expect each and every coin to follow it though.
In the second half of 2017, when there was a general rise in the cryptocurrency market, almost all types of cryptocurrencies grew in price. Then the market was still very young and its participants did not have enough experience. Now the cryptocurrency will not grow in price so massively. Investors will only invest their money in projects that are clearly promising. And there are not so many of them.
At the same time, DeFi projects can still repeat itself, as in 2017.
