To translate mpoe pr's post:
"Any centralized exchange besides mpex is a pretend play exchange because they don't have 30btc registration fees and an options trading bot. Stop using useful stock trading services like Havelock and give us your money because we are smarter than you." - mpoe pr
Anyone with an IQ above 13 could see that decentralized exchanges would essentially make the only feature mpex offers (secure trading) obsolete. This ist assuming there are even still people who think mpex has a solid system for trading.
I am almost sure that it is possible to find at least one person with IQ 15 who would not see (nor understand) this.
