1. US is the IMF reserve and the manager of international loan policy.. they can rig their own credit rating.

2. defaulting to other countries can be cured by a few things, such examples are:
a.the loans it makes to other countries can be cancelled out against the loans other countries made to the us. 1for1
thus bringing the amounts down. (writing off debt)
b.rigging the forex rate to change how much breadloaf/labour value of money is owed to other countries
EG if $1 =€1.10 they can change that to €2.20 and half the debt owed by measuring the debt in €expected back to the eu

3. the US can just QE new money domestically without needing to get loans from any countries

..
with all that said fiat is a scam.they can create as much as they like and dont need a vote from their populous to loin in or out more either..  they tax you where taxes are suppose to pay for public services for the populous to benefit from.. but they are now finding excuses to not pay for public services (road/bridge repairs/emergency services) and instead want taxes to pay the rich corporations that dont offer public services. yep the populous pays into the tax treasury but no longer get the same amount out in public populous benefit/services

bitcoin however is not tethered to US economy even if its priced in it. bitcoin has its own international community where bitcoin has its own usecase and functionality meaning its own price discovery,

that said if we use a breadloaf value/labour value EG $7.50 was min wage now moving to $15... $1.25 was bread now $2.50. bitcoins growth has exceeded that in deflation in less time. so dollars inflation doesnt pair to bitcoins deflation

when people hate the dollar they cannot exactly move 100% to another currency for daily life because fiat still controls things like wage requirements, taxes, bills, debts. however some will try to find ways to lock value up from their savings into crypto investments.

however the large traders that could affect the crypto market price substantially will do OTC trading, meaning not directly affecting the bitcoin price.

there will be some price drama. but it can go both ways
people losing daily spend fiat lifestyle ability will sell their investments to survive a fiat life. or those already settled in a cozy fiat life with no debts/payments to make to survive will invest into crypto

...
however the downside is limited.
bitcoin has a fundamental infrastructure "bottom" which aligns with the lowest most efficient mining cost on the planet.
no one wants to sell for less than anyone on the planet can mine for. so unless there is a mega hashrate drop. there is a bottom that is non zero. at the moment this bottom was $15k moving to $20k. which means the downside can only go to $20k but the upside this year so far can go upto $130k due to same fundamental measures of the same, for the tops

no one knows the amount, timing or price it can be in the future but the signs are there would be more of an upside chance than a downside chance in the near future. but no one knows for sure.. it can go both ways

QE will be good for the crypto but then they might not like it as well. And it will result in people not trusting USD. They do have options like raising the debt ceiling or just cut spending.

Recession will come like 2008 and cycle again. It will keep going and will have another recession in the next decades.  The fact that it keeps coming back, there is no real solution to this.

What if I tell you that the US is already in debt since the 2008 crash? They just simply print more money to balance it out but that doesn't mean the financial condition of the country is doing good.
What if you are told the wrong reserve values and the actual reserve is something different? Here I am talking about gold. What if they are selling gold reserve to fund their economy?

In debt, oh yes, tremendously, and getting worse with no probable end in sight.  

Gold no longer backs up the U.S. dollar.  What really backs the dollar and keeps it value is the confidence people have in it.  Confidence expressed by every single transaction that uses the dollar.  Confidence supported by the ability of the U.S. to produce goods and services that may be purchased with the dollar.

Regarding the original question: I suspect there is no person, or group, who has sufficient information to make a solid prediction.  But, I suspect that world wide cryptocurrencies will tend to go up.

Don't be dramatic. The US debt limit is $31.4 trillion, and the current level of the US national debt is $31.7 trillion. The debt ceiling was reached on January 19, 2023, in other words, the technical default has already occurred.

I do not think that it would be possible for US to ever default on their debt at all. I think the best thing about US debt is that it is unending and keeps growing and you could always trust that it will keep going bigger and bigger. They were talking about just a few trillion dollars which is already a lot, just a decade or so ago, and now they are talking about 20+ trillion dollars easily.

I am not sure when it was but I remember it was about 4-6 trillion range and everyone was going crazy about how huge that was, because not many nations in the world could have that much, USA could be the first one to get there probably. Now it is 5 times that much and people are acting as if that is normal and they are going on, so they would never default it when they could just make more of it.

They've already tried printing more dollars out and it's resulted in inflation. They used the funds to create a social welfare state during COVID and they accepted inflation as a consequence. Modern Monetary Theory states that no country that prints its own money will go bankrupt. And there is no doubt in my mind that they would replicate the COVID strategy again if they needed to pay of debt seeing their adamance to spend money that did not exist during COVID.

Debt isn't inherently bad. If the U.S. had the economic growth to sustain the liabilities they were taking on then it would be a different story. Except the debt to GDP ratio has been disproportional since Bill Clinton was in office so you can't count on the U.S. ever paying it off.
