The highest I ever paid was ~$510/BTC for about a third of a big one.
Bitcoin is supposed to be for everyone, not just the wealthy, so are you comfortable spending $50 (for example) for less than 0.1btc?
Have you ever paid more than $700/BTC for any amount of Bitcoin?
I have experienced paying more than 700 usd in BTC. That was way back 2014 when I bought 4 pcs of 1TH miner. And the added cost of custom tax. It was ordered in China and delivered in Australia. the miner cost around 0.8 BTC each and shipping fee of 0.56 BTC. Those time BTC is ranging from 250 usd to 350 usd
