And of course, Bitcoin Cash, which some considered the "main competitor" to Bitcoin, has lost 99% of its value relative to BTC.
With the way bitcoin cash (BCH) was, it should be very easy for people to know that the coin will lost it. The coin that its developer named bitcoin to deceive people as if it is the real bitcoin, but which people that are in crypto that know about what was going on know as an altcoins. The airdrop alone should be a reason most people should also know that it would be a shit coin.
People should realize that any coin that comes as an airdrop is mostly not good for long term investment. You could take examples from previously airdropped coins like Arbitrium, Uniswap, Jupiter, Starknet and the rest. They don't have long term utility and it's definitely not good enough to compete with bitcoin, not even now or in the future.
Many of the altcoins follow a certain pattern, and one with the experience and knowledge would immediately identify a scam or a rugpull project without a hassle.
