That's what I do. I'm trying to accumulate as much as I can because I know that this is going to rise again and $10k would be just another target for us to keep after hitting $5k or so.
The demand isn't going down but even with the fees goes on high, there are a lot of people that have been buying it. That's a sign that ETH is doing good despite it has been down from its all time high.
Yes. Fees haven't affected ETH's demand on the market. On the contrary, people are buying more ETH to stock it up for the next bull market run. Before ETH goes to $10k, it's going to need to get past the $5k mark. With how fast ETH has grown within just a few years since its inception, going all the way to $5k is a piece of cake.
I have a feeling that the upcoming upgrades on August 4th, will trigger a massive boost in ETH's price. We might end up the year with ETH being worth at least $5k per coin. Investing in "De-Fi" platforms with your ETH could even leave you more money in the long run. As long as you buy low and sell high, you'll have nothing to worry about. Just my opinion

It is in demand and strategy of most of us.
While we understand that the bull run has already been done but it doesn't stop us from thinking of the next possible bull run. And that's likely to happen if not at the end of this year.
We still got the next year before it fully goes into bear.
