But BitcoinBTC maximalists "selling" it since 2015 as an alternative for payments.

But in last 3 years there were lot of adoptions of BTC Bitcoin mainly on trade markets.
But still no real daily market where the people use bitcoinBTC as a payment - just get out and try to buy a food for Bitcoin - almost impossible.

Limitation of amount for a coin like bitcoin or any other altcoin as well low inflation makes it only worth to use as wealth storage.

Gold were also a payment unit till middle of last century, but now it is only wealth storage and speculation object on market.

Same is and will be with BTCbitcoinBTC it is to volatile to be used as payment.

Except Satoshi Nakamoto will defreeze his million BTCbitcoinBTC
