nope its true according to
https://www.similarweb.com/website/bitcointalk.orgbitcoin talk is losing around 2 million users per month since march, i think users will migrate to other forums, doing a linear prognosis then we can expect this forum to be dead in around 9 months
Hhahahha no. I don't think so. Where will they migrate? bitcoin.com? I don't think so.

bitcointalk has been getting less users because of the new merit system; and I'm pretty sure about that.
Also, dead in 9 months? You wish. I don't see this forum dying even in 9 years.
coinmarketcap loses 14.22 million users per month due to decentralisation of the market. coinmarket cap has also max 10 months left but i doubt linear prognosis works well so double the time would be more realistic as it will be a recessive loss.
So? That's because there's better competition. We have LiveCoinWatch now, which some people prefer over Coinmarketcap. I don't see how you see this as a bad thing.
