This is something I've been noticing for a while, across both fronts; the P2P on-ramp exchanges and trading scenes.
The problem is, instead of offering goods and services at a discount when paid in XMR to promote Monero usage, some sellers and service providers are instead charging a premium for it. This also includes the XMR sellers over at Retoswap where they post horrendous Retard Tax selling Monero. Or in the case of XMBazaar, why would I buy an item that's incredibly overpriced there, and not just get an Amazon gift card from XMR.CARDS or something and buy on Amazon directly ?
All of this leads to the opposite effect and actually hinders and discourages people from using Monero as a currency.
Obviously, not telling anyone what to do here, one is free to price their stuff however one wants. Just presenting forward an issue I observed in the community.
This also leads to another issue specifically with XMRBazaar with how it seems there's just way more sellers than buyers there, in combination with the large number of low-quality listings, it's almost like people are using the website just as a way to earn Monero regardless of proper marketplace quality. But this specific bit is perhaps a different topic.
Interested in hearing you all thoughts on this.
