First of all, I sympathize with you, I myself think that ETH price will surpass $500 in August thanks to the very strong momentum last week.
I hope that this opinion of mine will not affect your decisions much in the crypto sector. Simply refer to it!
ETH 2.0 is about to be launched with POS, and as we have seen, a lot of people are willing to join this network to gain passive income from staking ETH. I think this will have a positive effect on ETH price in the future, meaning $500 is a viable price for ETH in 2020.
