If I sell my used stuff I want to choose which currency I get.
There is a lack of new trading platforms (similar to old eBay, old Amazon, old Alibaba) which offer their customers to choose receiving their desired cryptocurrencies.
These are free countries.
They have to stop forcing us!
They have a monopoly but they dont "force" you to do anything as such. You can either use them or use something lik open bazaar. The problem is though everyone uses ebay etc. I dont know why they dont allow you to accept crypto in some way though, ebay will argue they cant force a refund if the buyer has a problem with the transaction. However ebay give you the ability to mark as payment received if you deal with cash for example on a trade you've made person to person.
Maybe ebay could have a feature where you put a certain amount of money/crypto in escrow with them while the crypto transaction goes through. This kinda feature would only be needed if you had little reputation on ebay anyway. I know just recent i bought something via paypal and accidentally did it under the wrong account so i did not have any money in my bank connected to the paypal but because i had a large history with ebay/paypal they covered the cost and put my paypal in negative amount until i repaid it later.
