It wont for now. BTC is launching engines and will soon lift the cumulative market cap to 100 billion. That said, the combined altcrypto capitalization will shrink and one day cross 1K usd coz alts aint worth anything and have no utility in real world applications.
You may be right, but Bitcoin is not ready for mass usage. It is having hard time sending the transactoins just now, the mempool of Bitcoin is flooding and the fees are going up because people don't want to wait 20 hours for one tx. people will start using other coins for paying for their pizza's and coffee, Bitcoin can be gold, but in the current state it's not ready for million transactions. Scalability is a serious problem for the longterm and I glad Ardor (and other projects) see this urgence and try to figure out that problem now. Eventually we will have an advantage.
