There are hundreds of shitcoins lying around with nobody investing any amount in it and it's quite obvious too.
Its because those coins were target for pumps and dumps by investors who dumped on potential bagholders at the moment they got listed on exchanges. Its a specific breed of investors who jump from one ICO to another ICO. This was much prevalent during the 2017 ICO craze when bitcoin rose to All time high prices.
Why would people invest in projects that has no potential. It is obvious that not every coin would gain traction hence the low price.
A low price does not mean a bad project explicitly. Then again majority of these altcoins dont have anything worth investing in.
The projects that are potential will definitely gain an increase in the price of its coin.
I think we should focus more on bitcoin than any altcoin because it is the one that will definitely grow in future owing to its deflationary price.
