Please check out this site:
https://www.joinsnapcard.com/ from what I understand snapCard is a java plugin for browsers (any work) that allows you to purchase anything on: eBay, Newegg, Amazon, etc. for BTC. If you're looking for some reassurance (which I can understand) please check out their website and also the popular show "Let's Talk Bitcoin" where they review with the developers how this browser tool works. They've had purchases of .02 cents (USD) up to a new Mercedes at a dealership in Texas (valued at over $60,000). Also I would greatly appreciate any donations you can spare of BTC or DOGE currencies:
DOGE: DBuAQUUTttWYfsCkoEo6C4osdJgXpo9SJi

I hope you've found this helpful and this opens your eyes to a more realistic value of cryptocurrencies.
Thanks for reading!
