Bitcoin maximalists refer to people's who believe that Bitcoin, which is the world's most popular cryptocurrency, is the only digital asset that will be needed in the future. All other digital currencies are inferior to Bitcoin for Maximalists. The maximalist ideology holds the view that other cryptocurrencies are not in line with the ideals that were established by Satoshi Nakamoto, who created Bitcoin in 2009
"Bitcoin maximalists believe that Bitcoin is the only digital asset that will be needed in the future." Definition from investopedia, which is what @valse posted. Probably doesn't capture everyone's sentiment. I'd say it's that the only thing worth bothering yourself with is Bitcoin, and altcoiners can burn themselves out to their hearts' content.
But more importantly, is a Bitcoin Citadel also a "Maxi Pad"?
"Crypto" is scams that ride the coat tails of Bitcoin.
Decentralization doesn't need a token, and using one skews incentives and wastes resources that are needed for decentralizing which is hard.
We don't need lots of Internets, we already have one. Same is true for Bitcoin.
