In the last few days, I looked at the exchange rate and saw an increase in USD in any currency so that some countries experienced inflation and crisis. I don't understand why USD can rise so high? Does this also affect the decline in the crypto market? 
USD going strong does not mean inflation.
Inflation is something internal to an economy, and essentially means a rise in prices due to the debasement of currency or easy credit. However, USD rising in relation to that particular currency doesn't necessarily mean that prices in that country is all of a sudden going to soar. Only imports from the US will increase in price, and that is only a small proportion of the goods on the market.
Nor does it mean "crisis", unless you're the one actively trading USD and holding a long position on it, because some countries actually actively devaluing their currency to be more competitive.
Good sir, you do know that most 3rd world currencies are backed by USD and not GOLD right? So if you think that USD going strong does not mean inflation and it does not mean anything to a country's economy, you are wrong. Considering the world economy, we will be seeing more how USD get stronger and other world currency to go down. And that thing is really really bad.
