I sold about 10% of my stash. I'm not sure whether the bubble has burst or not, but I decided I'll take some profit (bought at sub $100). We might see $5000 or $10000 in the next few days, but I'm pretty sure the price will go down to $1500 (or even lower) at some point in the next few months or next year, and that's when I'll buy more. If that doesn't happen then it's fine, I'll invest in something else.
What do you think of my decision?
I would say your decision is like asking for a miracle or should we say a disaster? The prices might go down due to panic on August 1st but I don't think it would go as low as $1,500 anymore. The price is high right now because of the recent good news for bitcoins all over the world. It is being adopted by a lot of countries and there are a lot too that recognize its potential. Take Japan for example, they passed a law that implemented bitcoins as a currency in their country.
