The customer service is amazing! They are always willing to help you with any questions or concerns that arise, they're super friendly & easy going people who make it fun for me as an investor/trader when I am trying out new things in their platform. Their charting tool has been very helpful while learning about technical analysis of different markets which helps keep my trading consistent (which can be tricky sometimes). Not much at this time other than giving them some feedback after using them awhile so far but overall everything seems great thus far. It's hard not knowing how well your portfolio will do once its launched into full effect because there really isn't anything else like crypto-currencies right now since we've never seen something quite similar before where one currency could go from $0 - >$1000000 overnight without even having more users coming online all together until then.
