That's a problem, because when you're teaching people to program you often find that anything that needs a credit card at all is a blocker.
Young people often don't have them. People from other countries often don't have one that works. People who work for organizations often don't have the ability to spend any money at all for work they are doing that relates to that organization.
Best data I can find is that only 50% of US parents have let their kid use a debit or credit card for online purchases (and many wouldn't do it again). I think it's incorrect to say that 50% of American kids should be written off.
That's short sighted. Getting a credit card when under 18 or an unemployed student isn't possible. Those are the people you want learning on your platform because later on they become your valuable knowledgeable customer.
I have a debit card but not a credit card (and can't get one). I'm locked out of many hosting services, which don't want to allow me to pay up-front. It's very American-centric and annoying.
i wonder if it's an admission that these hosting services don't have billing sophisticated enough to alart when you hit a limit, in this case of the debit card's available balance?
