Until a few years ago, altcoins were not this famous

After the high price growth of altcoins at the end of 2017, altcoins are almost 90 percent in price and have not been growing for two years. Therefore, it can hardly be said that in recent years they have added to their popularity. Yes, despite this, altcoins are still developing and the time of their popularity is yet to come. To do this, they must show their real usefulness.

Most people invest in altcoins because they know that altcoins show more growth and make more profit when the season of altcoins begins. Another reason why people buy altcoins is that altcoins are cheap. Bitcoin is expensive and not all people can buy it. I believe that altcoins are a good investment (not all) if you know what altcoins to buy

Until a few years ago, altcoins were not this famous. But now, most people want to invest in them. What’s the reason? Why is that altcoins are becoming so popular today? I read this blog- https://www.coinspeaker.com/altcoin-analysis-2017-2019/

lets begin with why bitcoin all of a sudden became popular, that's evolution and we expect to see more in the industry. Time will come when more people will not be happy they didn't go into any cryptocurrency. Although there may be the other side of it but with the look of things,  cryptocurrency is becoming more stronger

Cryptocurrencies are a highly speculative asset class which can increase and decrease in price at any given moment.Volatility  in the altcoin market is a great way to increase your holdings and potentially make some good profits.

As for altcoins, it seems to me that as the crypto industry develops, new, more technological altcoins will appear and they will displace their less successful counterparts from the market and this process will occur constantly.

The cryptocurrency market is still in its early ages. A few years ago there were not even many altcoins, when the bitcoin earnings increased and when people saw this as a get rich quick option tons of altcoins were live.
Also great projects had the opportunity to born at these times like ethereum.

A few years ago, altcoins could be counted on the fingers, and no one even believed in bitcoin. Further, after the pump, people's opinions began to change, a lot of altcoins appeared, but only a few of them became famous.

Altcoin are not famous long ago because it has no unique use case compared to bitcoin. People have interest nowadays in altcoins because they witnessed or heard the massive gains of altcoins in the bullrun.

The popularity of the Altcoins was slowly fading away because it was badly damaged with those scams that victimized a lot of investors that's why I'm not wondering why many investors are keeping a distance to the new ICO and IEO projects nowadays except those potentially cleared projects from those bad actors.

Its because there are altcoins that have unique use cases and can be used in the future. There are use cases of altcoins that bitcoin can't do that's why the trend for altcoins is outrageous. And I still believe that there will be more altcoins that will come in this market that are not copy-cat of what we have right now.

Not not famous but not yet famous and so many who complain why it all happened? What things affect altcoins not interested in?

I believe the OP has little experience with altcoins currently on the market.
Because the OP is only complaining about the state of the market and I'm sure the OP also needs a little refreshing with its money near the beach and seeing the beauty of the sea while looking at the green altcoins in Binance.

Investors invest in altcoins because they are well aware that they can bring them big profits in the future. This is one of the main reasons why people invest in altcoins. The second reason is that some altcoins can be used for your own purposes.

[Nestle]

Because a lot of profitable and interested altcoin is growing. Right now I see altcoin growing and better than last year. Maybe in the future altcoin will be used more by people as an investment.
