You're buying pornhub premium, aren't you? Unfortunately, I also wanted to buy something from a site that only took crypto as payment.
I ended up creating an account on Coinbase, which required a whole bunch of personal information from me. That was very concerning, but they seem like one of the few crypto sites that aren't totally shady. It's apparently a law they must follow to tie my personal information to all my crypto trades to prevent crime or something. After they verified my government IDs and bank account details, which took a day or so, I was authorized to buy crypto.
I bought the exact amount I needed. It took about 35 minutes to confirm the transfer, and only then did I realize coinbase takes a fee, which means I actually had less than I needed. I buy slightly more crypto, wait another 30 minutes for all the super cool futuristic cryptoblock hashing to be completed, and now I finally have enough crypto to buy that $20 thing I wanted.
I tell coinbase to send my 0.0000018364929038484920385 coins to xhfhfosnjwifbgnsoahdbfiaojdbfidhsbdmfodhsbd and the site eventually confirms the transfer after yet another 30 minutes of hashblocking.
It took me about 2 days and $30 to buy something for $20 using crypto, and I have never hated crypto bros so much ever for believing this is how all payments will work in the future.
Edit: I forgot to add that ever since then I receive a dozen crypto scam emails a day.
