I used ApeBoard before to manage my small private portfolio. But after transfer to nansen all BTC accounts show zero! When I asked in discord, I was suggested to upgrade subscription. I like to continue using nansen portfolio, if (and only if) it supports same features as ApeBoard does befor.
You can view BTC without having to upgrade! Sorry for the miscommunication. I think there're usually some bugs on BTC and we are working on it ser :)
