There is another website for "Bitcoin is dead" chart is
Buybitcoinworldwide.com but the team behind it stopped updating the chart recent months.
Just ignore them.
The more we visit their website, the more they feel they are noticed by us and the more visitors they get. whether they are actually haters or not, what is certain is that they only want profit from what they say. And believe me, they will stay that way as long as they are working for it. Haters will always gonna hate, no matter what we explain. Soon, more people will become aware and will turn to love Bitcoin for certain reasons or even without significant reasons.
I think you may have misunderstood the purpose of such sites. They're not really trying to be taken seriously or anything. A lot of times they're made by Bitcoin fans who are just joking around about the crazy predictions some people make. Its more meant to be sarcastic humor than an actual prediction to take literally. I mean, those sites are just poking fun at how wild some of the Bitcoin forecasts can get. It's all meant in good fun from people who actually like Bitcoin overall and they're not really taking critical swipes at it by making those parody prediction sites.
