If you have money then you should buy bitcoin right now. If you will wait until august perhaps its price maybe higher than today. We do not know what will happen on August but I would like to think that its price will not be affected.
It is rather unfortunate that a good number of fellow bitcoiners here are groping in the dark out of sheer laziness or insatiable greed for more coins that takes their eyes off things going on around them but I used to hear that a man's heart is always where his treasure is.
Come August 1st, the Bitcoin network is scheduled for a soft fork and not a hard fork. The proposed hard fork is slated to come up 6 months later, until then there won't be any split of the Bitcoin network if at all there would be one!
Essentially the soft fork will start to ease one or two of the issues affecting the network. Is it a time to run for cover? Would you rather join the panic party and dispose off your coins only to pay more for them after August 1st? Life is full of choices - becoming wealthy is one, so also is penury.
