I agree crypto is likely to do better while dollar is not rising, they are both globally used currencies.
huge infrastructures that are being constructed. It seems like the USA has done already some advancement and that is why their fiat currency has gone strong
Infrastructure must be paid for and give a yield to really be justified, the Hoover dam took decades to return value and its building required government approval giving politics a lead. The problem is the debt raised in the name of that infrastructure spending, China has a similar idea but again some of the results have given no benefit to the economy and certainly not enough to repay the debt. This adds upto currency weakness, without a rise in tax revenue from greater business done the spending and borrowing in dollar is not justified. The only thing that happened recently is greater amounts of debt, due to a rising deficit in fiscal budgets.
The reason dollar index rose is that is measured against similar FIAT currency in some cases also being printed in greater numbers. The market favour and mostly in speculation that Dollar is the safest long term currency. Its true till it isnt and its already the case that USA does not export enough to repay this debt to the world. That could change but also likely to be at the same time dollar value is lower.
The only alternative to this scenario is a greatly reduced government expenditure, higher rates, a surplus in the budget and debt being repaid. All those effects add upto and justify the view of a strong dollar, otherwise many currencies are devaluing but in parallel which helps maintain the status quo shown in the dollar index value ; this is not strength anymore then a coat of paint is a repair
