If you play games on PC, you (should) know about Steam. You can buy Steam vouchers with Bitcoin and Litecoin. It also supports Dash and Bitcoin(Lightning)!
Here is the link:
https://www.bitrefill.com/steam-eur-voucher/
The price is in Euros. 50 EUR is roughly 62 USD.
I try to send both with Bitcoin and Litecoin to see how the transaction fees differ. To my surprise, Bitcoin(segwit) had lower fees! For bitcoin fee was $0.10, for litecoin it was $0.17.
But for whatever reason the conversion rate was better for Litecoin. So I purchased with Litecoin.
You can also top up Viber from bitrefill. Bitrefill also supports prepaid phones for major carriers in South Korea.
