Coins are more expensive there but it works fine. If you are verified on other exchanges its most of the time cheaper to buy any coin there, transfer it to an exchange that has iota and trade it there.
IOTA is a good concept but has a lot to work on until it's ready. Lot's of hype that fizzled out due issues with wallets and deals not going through. With all that said they are making deep connections with different companies and manufactures.
As it stands it's still in the air and a gamble. It can pay off big like any other crypto but that depends on use case and speculation. Don't put in more then you are willing to see go to 0
