Fully agree, every merchant is a loss, when there are so little...
Was Tor2door a significant player? I really don't understand why nowadays markets without payments "per order" and multisig escrow still are a thing.
I came across Bitcoin in 2011 when Paypal freezed my business Paypal account and a mid-5-figure amount for 'at least 6 months' for selling Absinthe which is perfectly legal in Europe and more than a year ago they audited my shop and approved it manually. I had to hire a lawyer to get my money out without waiting their insane 6 months, their revenge was cancelling my private account and my girlfirends' too and giving me a lifetime ban without notification, but I tried to activate it again and writing to support even after 10 years, no chance.
Well, Bitcoin didn't work well back then (and doesn't until today in my opinion), but despite the fact I was selling my stuff with some other credit card and bank processing, I stayed in Bitcoin for years. Until the block size wars went insane and I proposed to solve it by doubling the block size every halving but have been laughed at by several Bitcoiners I respected until then. But I was pretty sure, I can't be the only one to think a fixed variable for the space available for transactions and searched for other proposals... Until I came accross Monero in 2016.
Until then I was a Bitcoin maximalist, since pretty much all coins had some kind of scams built in and I started searching for the scam in Monero... And I'm doing it until today!
That's really a pity after already cake pay web has been shut down.
Maybe take a close look with whom Bitrefill, Coincards, AllArk and others are partnering? Sure, you had probably the best value for the money but hey, better have a bit more expensive alternative rather than nothing.
This is a great idea for a service, however it needs to establish trust that it's not colluding with anyone. If it was a well-known member of the community, it would most probably be more convenient than it is now. Anyway, lowest amount you can secure is 1 XMR but your fees up to 1 XMR are 5% but there is 1 XMR min? All in all the fees seem reasonable.
