Jaime Warlock is one of the frequent users of digital currency service Bitrefill which enables one to buy pre-paid local airtime using bitcoins.
The site allows Airtel, Orange, Safaricom and yu subscribers to buy or receive airtime via the website, among other telcos.
The platform, though created in Stockholm, Sweden, has gained popularity among the more than three million Kenyans abroad who often send airtime to their loved ones through Betrefill.
“I find using Bitrefill to be much faster and more efficient than using a debit card here in the US. I just have to copy and paste the Bitcoin address and the amount to send,” Mr Warlock said in an email conversation.
