We are all expecting brokerages to do more with cyrpto.  Many are hopeing for a chance to be charged a yearly fee with an etf, an excuse idea that is truely bazaar.

There is no reason from a technical standpoint that you can't have a partially functional wallet instead.  Maybe you only really need to be able to send out to one addres or maybe there needs to be a withdrawal limit.  It's only a matter of time before crypto invades the space but perhaps the way it will work when it does is still to be decided.
