There is a big problem with this Fee market that should be resolved asap. While many wallets allow one to adjust the tx fees or even selected between different fee priorities , only 1 thus far that I know of automatically calculate realtime (bitgo) tx fee priorities so the user doesn't need to look them up with a service like
https://bitcoinfees.21.co/#delayThis could easily be implemented , but is one of the temporary negative side effects created by a tx fee market.
It seems the cause of the problem is Core 0.12 nodes and miners not relaying valid transactions, causing the mempool to expand.
I'm banning all 'classic' and XT nodes as transactions sent by those spammers are not valid transactions. They are altcoin promoters.
Reminds me of luke-jr filtering out gambling tx's . I suppose every node has a right to restrict relaying certain tx's amd every miner has a choice to include a tx or not.
