AFAIK, there are only two ways to hold stock in your own name.
One is to get a physical paper cert. I have to deal with a paper cert in the past and it is a huge hassel.
The other is to use Compushare who is NWBO's transfer agent, This is a minor hassel, you can ask Senti or some others if it is worth it.
Using a cash account is simple and has only a few very tiny issues for those who do not run a margin deficit. Basically you would have to wait a few days at times for funds to clear while in a margin account you do not.
