The scam is selling hundreds or thousands of BTC in fee shares for 0.4 BTC each that he has no intention of ever paying fees on, weeks before shutting down.
Telling everyone to withdraw their coins, making him plenty more in transaction fees, unwithdrawable dust, etc. It also gives him cover in case he ever has to talk to authorities after he disappears with the rest of the coins in his exchange. Everyone has to withdraw because he has to do his testing on the live site? Can't create another DNS record and vhost? Maybe he could use some of his millions for a dev server?
Nobody is being forced to do anything. If it was a "scam", Real Solid could just shutdown the exchange and that's it.
And nobody was forced to buy any mcxFEE. The only ones who sold mcxFEE are desperate people who didn't understand what happened.
Now Real Solid decided to resume Mincoin/Solidcoin trading and charge for the support in case the problem was caused by the user (lost password). This will make a lot
easier to do the support and benefit all users.
This is free market. If someone doesn't like mcxNow, use Vircurex, BTC-E or even "Cryptsy" (the worst exchange ever).
