I tried sending some tokens and I can see the transactions on and off https://etherscan.io/tx/0xd9ec1b20c8d959ca95609bd0ee9fa6c2cf7321f160b4689580519440daebd4cb tokens are still I my wallet through, were you in the same case?
Contract 0x1a95b271b0535d15fa49932daba31ba612b52946 (MinereumToken). Then it shows as unconfirmed transaction in the block explorer for days or weeks. You check it every day and every hour and it is unconfirmed and you grow more and more desperate.
This is what I call a stuck transaction.
Of course, I am not sure if child pays for parent works for Ethereum network too. My OP was intended for Bitcoin users and if it was not clear, I am sorry to have caused confusion.
Also, currently the network is not stuck anymore
no it won't work with Ethereum and most of the altcoins out there because they have not yet admitted they have scaling problem and CPFP is a way to ease the issue for users and miners have to be looking for these transactions, there are even some bitcoin miners have not yet implemented this.
