The 'crashing' has been on the order of 10% per 24 hours or so. Actually BTC is about where it was a few weeks ago- not much of a crash. Open an account on Coinbase, place your seed order, and then buy the bitcoin that you need a couple minutes before completing your seed purchase. The 10-20 free seeds you get for using BTC more than make up for the $3 transaction fee. As for running up the cost of bitcoin, my $100 transaction isn't doing much to the $10 billion bitcoin market!
