No, it will probably not go down, even if it dips down a little, it will never reach $1500. $2000 could be your best hope. If you watch the charts closely, you will know that bitcoin is rising steadily, and gets small corrections along the way.
it could easily flash crash to 1500, that said since this is shake 100 + n you have to wonder who exactly is left to be shaken out ... I mean how many time would anyone holding any siginificant amount of BTC have already sold out if they were going to .... there are I feel less and less of those people left standing.
Any one that held to sell form the 2013 high could have sold out by now at reasonable profit.
Yes I believe as on the 1st August we will see the fate of the bitcoins that what happens to it and if something discouraging was found by the users the price may fall to $1500.
I hope there will be nothing wrong on that day so that the journey of the bitcoin continuous to grow more but if something happened regardless then I am afraid that we will see a significant down fall in the price of the bitcoin.
