With the explosion of easy-to-use (relatively speaking) DeFi platforms during this crypto bull cycle, it seems we are getting closer to the tipping point where just holding cryptocurrency assets becomes sufficient to meet daily needs — closer to the point where needing to hold or use fiat becomes a thing of the past. If you live somewhere that getting a crypto-backed credit card is feasible, you may be there already.
By the title of this blog I don't just mean HODLing your favorite coin(s) forever... even if you want to take profits into a stablecoin asset, it is now possible to do so while remaining in the cryptosphere through CUB, RUNE, UNI, etc. as noted by 
It will be interesting to see what actual "sustainable" APYs end up being on these platforms when some of the hype dies down — I have a strong feeling, though, that even as the settle they will be much, MUCH higher than those available through traditional "high-yield" interest accounts — perhaps by an order of magnitude. The writing is on the wall for banking institutions that have historically offered customers mere breadcrumbs while milking their capital through lending.
It is now possible to "cash out" crypto income/profits into stablecoin assets and farm yields on top of these profits... without ever needing to utilize fiat to "realize capital gains." It has become much easier for the casual investor to flip gains into further gains without having to relentlessly day-trade, attempt to short the market, or buy a speculative asset and twiddle their thumbs for a few years waiting on the project to pick up speed.
So, imagine a world where an increasing number of companies see the great potential benefits of allowing customers to pay directly with cryptocurrency. And even for those that don't, yet — a world where all your common payment apps such as Paypal, Cashapp, Venmo, etc. support seamlessly swapping crypto for fiat equivalent at the time of paying for a product or service. A world where wrapping/unwrapping bridges such as Leo Bridge are commonplace and paying this way is trivially simple, little more complex than swiping one's credit card.
Then imagine that Visa, Mastercard, AmEx and credit cards ALSO support paying off credit card bills with cryptocurrency.
Then imagine a world where fiat as we know it becomes extinct as governments scramble to create their own (likely highly centralized) blockchain equivalents of official national currencies.
This all may sound far-fetched, but we are not really so far off this becoming a reality. Building infrastructure and increasing adoption takes time, but in our hectic, highly-globalized world — not as long as you might think.
Crypto is only a little over a decade old.

What will the global financial landscape look like by 2030?
