Demo for Binance DEX (decentralized exchange):

Currently, everyone holds Bitcoin BTC as their reserve trading currency.

That's because:

1. BTC has legacy status as the default trading pair.

2. Trading costs at traditional crypto exchanges are the same, regardless of cryptocurrency. Ex: Binance trading fee is 0.1%, regardless of coin. That's because transactions are done off-chain.

But we've all known the flaw in traditional crypto exchanges: if the exchange collapses or disappears, you lose all your coins, since you don't have any seed words or private keys.

With a DEX, you hold your seed words & private keys. If the exchange collapses or disappears, you should still be able to access your coins on the respective blockchains.

If DEX exchanges take off, that could be a fatal blow to Bitcoin BTC's legacy status as a reserve trading currency.

That's because:

1. Bitcoin BTC's on-chain transaction costs are 20-200 times more expensive than for other cryptocurrencies (like BCH, LTC, DASH).

2. Bitcoin BTC has a small block size limit, and can't scale on-chain, so as DEX trading volume increases, Bitcoin BTC's mempool & transaction costs will skyrocket, making it unusable.

RESULT: If decentralized exchanges - like Binance DEX - become popular, Bitcoin BTC on-chain transaction fees will become ridiculously expensive, and people will start looking for a new default cryptocurrency to hold / trade / spend. It will be the end of Bitcoin BTC dominance.
