IOTA is a centralized project which failed. Any money you put into it is the same as throwing it in trash.

IOTA Foundation Suspends Network, Probes Fund Theft in Trinity WalletFeb 13, 2020 at 23:22 UTC

IOTA Foundation, the nonprofit behind the IOTA distributed network, recommended users close their Trinity wallets Thursday after
multiple reports of fund theft.
IOTA
said it started receiving the reports Wednesday and
decided to shut off the Coordinator node in the network for further investigation.[...]
On Twitter, IOTA
said it is working with law enforcement and cybersecurity experts to investigate a coordinated attack that resulted in
stolen funds.
Dominik Schiener, co-founder of
the IOTA Foundation, did not respond to request for comments before the press time. CoinDesk will add updates as the story develops.
The coordinator is a central node which validates transactions. When you do not care about decentralization, the network is vulnerable to attacks. Free/instant transactions comes at a cost.
The coordinator was stealing people' fund.
Are you sure you wanna invest in such a project?
