If we are not updraging with time, someday CMC or CG will launch their own new forum that may affect bitcointalk. Inst it?
Do you know many cryptocurrency forums but Bitcointalk is still the biggest one, over many years.
Coinmarketcap, Coingecko have their forums, assume they will launch their forums, but think who will join theirs?
Altcoin developers and scammers or influencers with not much different than X (Twitter) platform.
