Domain trading is a crazy business.Why would a .dev domain cost so much?The most valuable domains are .com,.org and .io,I don't see the point of domains like bitcoin.dev and btc.loan.The average crypto user won't most likely run away from such domains,because don't seem trustworthy.
These specific domains are very short, that's what makes them attractive. A few examples here:
bitcoindev.com vs bitcoin.dev
bitcoinexchange.com vs bitcoin.exchange
bitcoinloan.com vs bitcoin.loan
In most cases these specific domains are way cheaper as well. .COMs are going for millions depending on the domain, while most of these specific domains well under the $100k mark.
Overall, domain trading is quite a shitty business to be in. People ask too much for certain domains while they only appeal to those who are looking to actually utilize it and have it become a brand.
