BITCOIN TO CRASH on AUG 1st !!

Hello Guys,
A friend of mine working in the Block-chain bus. in NY told me that a system crash is expected on AUG 1st and thats why the prices of all CryptoCoins is going down.
If BTC survives this technical crash on July 31st midnight, its price is expected to go up again and above 3k$. If not, BTC will have no use anymore.

Do you guys have any idea about this ?

I am concerned because I have around 5k$ worth of BTC (2.5BTC), should i sell them now or take the risk ?

and What about other…
