I wouldn't buy altcoins right now, because I want to gain the new "Bitcoins" on hardfork in October and November. But if you don't care, it would be the right time to buy alts. They will for sure go up, after the Bitcoin "show".
very good planning, you'll ignore the other altcoin jam Bitcoin to prepare for the upcoming Hardfork in one more week, hopefully later when it is hardfork the price will go up just like BitcoinCash ..
