This is a very good question. Many exchanges closed registration (Bittrex, Cex.io etc.) due to the fact that their servers could not handle the incoming amount of users. Some (Binance for example) have upgraded their networks to be able to accept new traders. The old traders were not too happy to have the network down for more than 48 hours, however most were satisfied with lowered fees as compensation. What does it mean for the market? There is more demand for the services, more demand for the coins. I believe that everyone should be able to have the freedom to enter these markets upon fair conditions. Not everyone is a professional trader, but everyone should have a chance to become one. It's a matter of education, experience and making good decisions. A growing number of traders shows that the cryptocurrency market is evolving. Growth means more demand and market expanse. It's a good sign for the cryptocurrency industry.
