If you had most of your holdings on safe ground, you would not be panicking. You have to decide what is best for yourself, but if I were you I would start liquidating my altcoins as early as possible. Bitcoin not only is safer, but could even cover your losses, especially now that segwit is almost guaranteed.
I agree with you, more secure if temporarily stored in real money. Store it in BANK.
Before the 1st of August BTC will slide, it's time to buy Bitcoin.
Yes Im definitely agree with you, it is the time to buy bitcoins and if you really want some e secure investment then you have to make some plan according to which you can make investment like invest money on bitcoin and ETH equally so that you can make yourself satisfy.
