Days ago, I noticed Bitcoin dropped to as low as $5,200+ and had I got the cash ready I would buy Bitcoin at that level. Right now the price is already in the $5,700 vicinity and might go a little bit further while we are waiting for the hard fork on October 25. In my experience, there were many weekends where the price go down a bit maybe due to lesser demand and activities in the market (though not all weekends have this situation).
Just continue on watching the market and if you are really interested to have some Bitcoin under your sleeves then just be ready with your money so you can buy in an instant when there would be some dip. Remember that every dip is an opportunity to buy cheap. However, if you are an investor who really have the money and is really optimistic about the future of Bitcoin, then any day can be a buy day.
Good luck on your Bitcoin adventure!
