I'm correcting myself, I was talking about lobstr being a custodio wallet. That's why they developed lobstr vault too (it's similar to the stellar guard logic).
What do you mean with ok? if you are concerned about how easy will be for others to get your ICO then it will be harder than with an ICO in the Ethereum network because of Wallets available, there are multiple options for assets in the Stellar network too︀ but they are more advance and less user friendly (stellarport, interstellar.exchange, etc). The only wallet︁ I can say it's easy for new users is Lobstr.
Now, the Stellar network is︂ good for STOs because you can prohibit people to have your security token (or freeze︃ the funds) and that way it's easier to tell the regulators you are not letting︄ people wash money easily plus it's really fast and cheap to send value with it.︅ For example in my business people exchange tokens that are pegged to a real estate︆ in just 5 seconds and pay nothing in transaction commissions (one of the addresses in︇ my system pay for all transactions fees which are less than a cent) without requiring︈ to be a custodio wallet (my clients have their own keys).
So what I'm trying︉ to say is: if you only want to do an ICO to fund your business︊ you should go to Ethereum where more money is and where it's easier for others︋ to buy your coin since it's the more famous blockchain for this kind of stuff︌ (and wallets available/adoption is way bigger). You should go with Stellar if you don't care︍ of raising funds and are more interested in what the chain can offer you.
