Cryptocurrencies are growing in price with the speed of light. Demand for them is growing as well, with the same speed. Demand has grown to such extend that echanges are exhausted.
During the previous year, echanges registered the record number of singups from new clients. binance alone once reported 250,000 new users per day, this is in addition to Coinbase, which reported more than 100,000 new users.
Many crypto-exchanges are not able to handle such numbers of new users, hence, they prefer to give themselves a breath before going on.
Bittrex is one of the platforms that officially announced a temporary hold on accepting new users, while others platfrms were reducing recision, functionality, closing some options for registering. Now, three cryptocurrency exchanges are not able to accept new users, and they have declared officially about it. Those are Binance, Bitfinex and Bittrex. Bitfinex is changing the infrastructure and is planning to reopen on the 15th of January, while other two platforms are silent about their plans to take some measures.
