Altcoins are the duplicate of bitcoin do what do you expect, they will fade away over time, because their purpose of creation wasn't to help solve any problem which bitcoin cannot, but to use it as a means to extort the public from their funds. This is why shitcoins are failing to increase in value because investors are saving the value of their fiat currency by putting it into bitcoin investment.

Only gamblers, and people who don't care about their financial well-being if future will invest in altcoins. One same person create a shitcoin and after dumping the project, he waits for a while and create a new project with a different name entirely but with the same intention to scam the public again.
