DO NOT INVEST IN COINS THAT HAVE ADD NO VALUE OR YOU CANNOT SEE ANY REAL PURPOSE, BECAUSE MOST LIKELY COINS THAT DO NOT MEET THESE REQUIREMENTS ARE SCAMS.
MAKE SURE TO ALWAYS CHECK OUT WHITEPAPER AND ROADMAP, AND THAT FROM THOSE TWO SOURCES YOU CAN ACHIEVE TO COMPREHEND PROJECT AND PURPOSE
I could see your anger well expressed as you typed in CAPS lock. It seems you have fallen prey of some scam coins.
You have however raised valid points as it is foolish to invest in projects that has no real world use case just with the hope it will pump. Most of the creators of these coins have fraudulent intentions, hence the reason to be very much cautious and ensure enough due diligence is done before committing funds to any project.
