Who said you cant mine on myetherwallet, yesterday i mined some amount on myetherwallet adress. Today i imported UTC file to the accounts folder and when i checked my balance over control command it was exactly the amount i mined, for any kind of problem i transferred that amount to my new linux wallet adress, no problem so far.
that is, all the hype?
The hype was the windows miners being told a windows wallet would be ready at the end of the countdown. Dev lied and all the miners with linux wallets were ready. Lots of people on slack for hours saying don't mine to MEW.
And i explained anyone who was interested that it is no problem to mine to any valid ethereum compatible address with an owned keyfile + passphrase - from my feeling a few dozen times.
I believe many of the minerpool.net miners did this, cause they were mining since block 17(!) at launchtime instantly, without the need of preparation time.
Come on, this is not the first coin launch, where not all (e.g. Online Wallet, GUI Wallet, Explorer, netstat, and so on) was available at the launch. The Devs only make the mistake to try it, instead saying "we will see what we have" or rescheduling the launchtime.
