So im looking to invest into bitcoin and because it's hard to determine whether price will drop or raise after 1st of August i have decided to invest a certain percent now, and the rest after 1st of August.
Is it safe to buy Bitcoins right now, and by safe i mean - in case of a fork, i have read some things about a chain being completely neglected as if it never happened. Am i safe to buy my BTC now and send them to my storage or is there a possibility in which that transaction becomes "neglected as it never happened" and the btc will disappear from my wallet?
Is it safe to purchase Bitcoins after 1st of August or once a fork happens? Any catches or things i should be looking at?

Just don't want to screw myself over because of my lack of knowledge. Appreciate all replies!
