Agreed, many investors are too focusing on gambling away their money and ignore red flags, e.g. the management gets rich no matter what happens to the underlying business due to large pre-mine or they don't consider competition from other crypto tokens in the same business or the investors simply don't care what the business does because of Fear or Missing Out (FOMO).
I feel crypto investors should invest more effort on building out the crypto ecosystem / network and grow consumer and business adoption and create legitimate use cases for crypto, not only invest in them as tokens for long shot gambling.
