This is a great time to buy.. I wonder where it will bottom out?...
Well, looks like 9.74 was that point, but there were plenty of chances under $10.
I have a feeling though there are a few new approaches for handling the "Weekend Dip".
1.) Coinbase, instant sign-up, instant purchases. When linking a bank account to a Coinbase account (available just for those in the U.S., for now), bitcoins can be purchased with a bank transfer 24/7.
The coins aren't added to the account's wallet until the bank transfer completes (two or so business days) but the exchange rate is locked in at the time of purchase. This is the first time this capability has ever existed for buying bitcoins.
2.) MPOE options. The exchange just saw what appears to be its biggest single-day volume of its options contracts. There were over 20,000 PUT option contracts sold nearly all at once over the weekend. (Someone is counting on a rebound in price!)
The reason that a "weekend dip" occurs is generally attributed to the imbalance where selling can occur 24/7 and there are no new, incoming funds arriving through banks (which are closed on the weekend) and any wires to Mt. Gox aren't seen until arrival on their Tuesday morning. But options contracts aren't bought as the result of a conversion from cash thus these transactions can occur on the weekend as much as at any other time. So options purchases on the weekend can help counter the price swing that occurs during a "weekend dip"
Though this exchange has been offering options for over a year now, their trading volume has just recently become significant.
3.) ICBIT.se - similar to MPOE, ICBIT futures contracts on the BTC?USD are purchased with bitcoins, so that too isn't something that needs to
"wait for Tuesday" to trade either. While ICBIT's volume isn't quite yet enough to impact the exchange rate much, it does offer 10:1 leverage -- giving anyone caught with not enough USDs on a weekend to lock in so that if the exchange rate rises the upside can be captured.
For these three reasons, the Weekend Dip's days may be numbered.
