The technology which runs Bitcoin (Blockchain) will have changes in the way it works.
Due to rapid growth of Bitcoin popularity (High demand) and increase in transactions, these changes needs to be done in order to improve its work (otherwise BTC will crash anyway...period).
There were several offers to solve the problem. The most popular is SegWit (Segregrated Witness) - which offers the solution
by reducing the amonut of transferred information. Of course..Not everyone agree to that, and some people are against. Also, SegWit might have legal troubles due to cut in signature information (you don't want to hear about that..Me niether).
So, in simple words, on the 1st of August major player in BTC network (some exchanges, miners and blockchain network) will switch to SegWit protocol (new way of how Bitcoin blockchain transfers information), and some may change to another alternative project, or not change at all.
If it happens, (Not likely...so chill) will create "temporary softfork" which basically means that BTC blockchain will work temporary in different ways. Then the situation in bad position. BTC can split to two different coins, like that happened with Ethereum: Ethereum and Ethereum Classic. So you can end up with BitCoin and Bitcoin Classic.
It's unlikely to happen, but people don't want to risk their money and some people might cash BTC before August 1 (something familiar? Yeah...That is what goin on now), so huge market collapse some time in July will be happened. So PRAY!
!May The Force Be With Us!
