A quick question:
If i give you a service to generate free disposable virtual debit cards with $0 balance would you like to try it? You can try these cards to access free trials on tons of different websites (including DigitalOcean, Netflix and tons of other sites require debit card to access free trial)
Looking forward to hear your response and interest.
In Europe at least we have plenty off free banks which offer that (Revolut, Monzo, N26, etc). Personally, I would just keep using them. I also don't believe anyone would pay for such service just to get a "free trial".
