It seems like this month of the year is one of worst months of cryptocurrencies so far. But in my own opinion what happening right now is just a step of every cryptocurrencies before their unimaginable price hike before or after the year 2018 ended. I know most of the people who have been in the crypto world for years already seen these things will happen.
Fiat may somehow affect crypto but I know things will get better once again. What will happen in the end of September this year will dictate that path of cryptocurrencies in the long run.
As of now I we can invest more on crypto, but I warn you to invest only what you can afford to lose.
