For digital ocean account,can i use my debit card?

because i have the debit card not the credit card…please help me to know

Use the virtual box to run ubuntu os for free.
BTW, you don’t even need to have ubuntu os, you can do all tasks in windows too. Just install Python in windows from here and start writing your code in python IDLE.
And for importing bolt IoT module you can run this command in windows command prompt: pip install boltiot

Unfortunately they only accept credit cards…But virtual box is always an option

If you have a visa or mastercard debit card, it should work
If it still doesn’t then i suggest creating a paypal account, as they are accepting it now
