I would've skipped buying a butterly 60gh/s and went straight in with bitcoin.

Would've made a 100% return in the past 6 weeks.

I use a few different wallet addresses, but if I'm ever receiving coins I generate a new wallet, pretty much so I can keep better track on stuff myself.

In terms of a new wallet for every single transaction, seems overly secure! (But maybe that is the best way and I'm just lazy!)

I'd stay away from mining hardware like the plague.

There are already a lot of people with some very powerful asic hardware that have their setup running as you read this. By time you received your order difficulty could have risen by anything from 25% to 100s%, depending on who you order with and whether they have a preorder backlog...
