I think it is a bit harsh to label IOTA a scam and personally I feel this is a word that is both overused and misused in discussions about crypto. I think that too many people with good reputations are involved in IOTA for it to be a scam. However I also feel that IOTA is a bit of a grandiose vision with insufficient intermediate milestones such as a functioning wallet. To be honest the history of grandiose visions becoming successful within the tech space is not very good. However if the IOTA team do pull it off and the project becomes successful it really will disrupt the crypto ecosystem .
