Running in both clearnet and darknet? Because there will be a lack of trust If it's only running in the darknet. We've seen in the past services that simply run with people's funds after having a decent userbase and because of the anonymity there, It's pretty much impossible to know the people behind these services.
I think that for now, an alternative is to use a VPN that runs through the Tor network and also use wallets that has Changelly or ShapeShift integrated like Exodus, Trezor etc. these are not asked for KYC verification (but It's very likely that it will come).
The alternative is good, for now.
Trust is a more complex topic than just saying "It's regulated, then it's trustworthy".
Exit scams happen all the time even with "regulated" services as well, in that when they scam you they just invent good excuses to justify the scam.
Take for example the regulated Bookmakers that block your accounts and cancel your winnings when you win too much, and of course they will invent credible excuses to justify that.
Now some of them, like Pinnacle, are putting the phrase "We don't block accounts" even into their adv banners on the web, so what i am saying is a known fact apparently.
Take for example Paypal and their dispute system. It gives you a fake sense of security, because Paypal is not going to properly investigate on a dispute in order to solve that in the right way.
If i am a merchant and a user issues a chargeback and returns my item, there is not guarantee that my item comes back in one piece. And if i send them a picture of the broken item, they will still not believe me and won't investigate any further.
IMO aggressive marketing and user feedback are the only things that determine the trust level of a service or person.
At the end of the day, the "tx confirmations" are just a particular type of user feedback, right? And it works, it defines trust. No need for regulation for that.
An onion service that is marketed properly and worked well for many years, IMO would gain people's trust despite being a dark web site.
