With bitfinx shutting down its service and coinbase being priced very high which other service do you use?
Hitbtc has the lowest fee at the altcoin markete, i'am using bittrex it has 197 crypto currency and has better support team than poloniex. it will be your choicegood luck..
News in the market is that Bittrex has locked many people's fund without prior notice and now asking for KYC. One must be careful in dealing with such an exchange. Tomorrow they may lock your fund and ask tax statement.
Have u used Hitbtc? Do they have any withdrawal limit for unverified accounts?
I do not remember exactly but there are limits. I authorize all my accounts.
