Both decentralized and centralized technologies (Lightning and Liquid) for instant payment are maturing, so in the future there will be more means to trade Bitcoin instantly off-chain.
Privacy improvements like CoinJoin continue to be implemented, so the future will provide more means to conduct private transactions.
In that sense, I see bitcoin as a more robust store of value than fiat currency.
- buying and holding actual coins feels feels like investing in other nonperforming assets, like other currencies, or art, or gold
- the world does seem to need / want a decentralized store of value that bitcoin provides
- if you are worried about fiat currency, then just don’t hold most of your wealth in currency, just keep enough float to cover expected transactions
- bitcoin seems horrible for actual transactions, as others have stated, it can do very small number of transactions per day
- some other crypto currency will nail the online transactions part, when that happens, that will be super interesting
The real value is once we get the cross blockchain projects that facilitate transactions between different blockchains. That will unlock the true value of all block chains, as they will be interoperable.
Not sure if FOMO, but central government abuses seem to have found yet another competitor.
However I do not believe that bitcoin itself will be that currency, for the simple reason that people are hoarding it, schilling it, and gambling with it rather than actually spending it.
Fiat currency is going to be around for while.
The only thing bitcoin is really effective at is speculation and manipulation by unregulated exchanges.
