Last time there were reasons which pushed Ethereum's price that high but this time I wonder what will make happen same. I fairly expect maximum $1k in case of repeating pattern of altcoin markets because this time market cap will be divided among more than one players. This doesn't mean Ethereum's importance is less but it isn't same powerful too. What is being worked on in Ethereum others are delivering before it.
Last time it was because of the rise of ICOs, right? ICOs were a bubble dream among people hoping to get rich fast. Though we may see ICOs returning whenever cryptocoins get mass attention again, they'll be more strictly regulated and a lot of people will have experienced or will have heard of the many scam ICOs, so I don't expect them to be a driving factor behind Ethereum. There are also many similar solutions now like ARK.
But I believe there's a more important factor supporting Ethereum, and that's the DAPPs. A driving factor with substance could be the gaming sector going mainstream.
I'm enjoying playing Axie Infinity right now and I see a lot of new players joining the Discord without prior knowledge of cryptocoins, they just come because of a great game and now they're buying Ethereum in order to play.
As this space moves forward, so could Ethereum. But don't expect 1000$ prices, if we take into account the amount of coins that are being issued, I believe this will be a TOO HIGH price to reach very soon.
Since I don't expect a rally sooner than Q4 2019, I take into account the coins that will have been issued by that time.
