A strong dollar will impact positively on cryptocurrencies. It is the most outstanding fiat the all exchanges have to exchange against cryptos. Therefore it will inspire confidence in the market.
I think if the dollar rises, of course it will have a negative impact on the economy in some countries.
For those who understand the crypto world, of course that will have a positive impact.
For those who do not understand the world of crypto will be a problem, because all their needs will increase due to rising dollars.
