I totally agree with you, true story I did a domain buy today, seller was asking to close via any top crypto currency, I had to pay them 5 percent extra to close via traditional means, only because they had to pay that % to the middle man for processing.
Cryptocurriences are practical and make sense for trade online, a few months ago, I was offered 3 BTC for a Coin + 3 letter English keyword .com, I basically told him I don’t care how or what I want $25K, at that point those bitcoins were worth about $14K, so deal didn’t make sense, he told me maybe wait a few months, and it could be worth that much, or more. He was right that deal is worth $30k today, $5k more than I wanted, domain is still in play, so not worried, as all deals don’t work out, but just an example to show you guys.
