I use Blockfolio too as it seems to be the most convenient app out there right now. Should there be any concern for tracking and privacy info?
mmm I am not sure that I am concerned, you really don't put any personal information in the app right? You just put in info regarding your investments. I guess if someone found your phone, and unlocked it, they could open up and see your porfolio of investments. But then again I am don't really know for sure! Hackers are pretty smart these days. haha
No you can put in your portfolio, but you needn't. I have put all relevant cryptocoins into my portfolio from different exchangers. So I can also use it as arbitrage tool. To put all coins of trading to blockfolio is for me to laborious, because that still must be done manually.
Still new definitely, heard about arbitrage, something I might look into doing in the future. Yes it is laborious, especially if buying a bunch in a day, but if you only buy and hold every once in awhile, it is not bad.
