Here's some reasons behind crypto market fall;
Different rules and regulations are being issued by the governments of different countries.
Most of the cryptocurrency exchange stopped accepting fiat, cryptocurrencies, and trading. Users are required to fill their actual KYC details to trade cryptocurrencies.
- rules and regulations have been issued for bitcoin for a while now. in fact last year the regulation of bitcoin by Japan and 2 other countries led to a huge bitcoin rally. so you can't say regulations is the reason for the price fall.
- nonsense. exchanges were always asking for KYC if they were accepting fiat. the big exchanges for instance such as Coinbase, Kraken, .... have always been requiring KYC and users to submit their documents. you are confusing some altcoin exchanges such as bittrex asking for KYC with bitcoin exchanges!
