Hello, it's not to late to get in.

Bitcoin has some big step in August but if everything is fine, maybe price is going to skyrocket

Ethereum has explode to 400 $ and just fall, it's normal in the cryptoworld, we can count the number of time bitcoin did it. Ethereum still has great feature to come (Metropolis) and if Ethereum follow bitcoin path, there are no reason to think it will not move upward.

Besides ETH and BTC, there are a tons of altcoins out there and some great projects. Do some research, just invest what you can afford to lose, forget it, come back in few years and profit.

Best of luck !
