My first question to you would be do you hold any bitcoin previously? if your answer is no, i would suggest buy few now and buy few post august, so that you can have a balance of price.
I have not kept any bitcoin before, which is something that I regret, so I'm trying to store bitcoin as it carries a relatively high price.
Sometimes it's very sorry because we do not store bitcoin, and sometimes buy bitcoin is the right decision to increase the money you have, but still it is risky to buy bitcoin at a high price.
