Proposal for discussion:
To create market attraction for both individuals and commerce, the best way is to distribute the access to the widest group possible. By combining a truly universal basic income that recognizes no borders, groups or authority, such a dividend would be most attractive to the poorest in the world. Even US 20 cents per day per family is a 10% raise to a billion people and would cause both the "productive value" and the highest velocity transactions to migrate to any currency that implemented it.
I've ran extensive numbers (still subject to critique though) and found that a mere 1% built-in transaction fee would grow the number of transactions and the daily dividend to the point where it continually attracts higher and higher wealth individuals. At first, this could be a couple US cents worth per family per day but when they spend that money, they must do so at a business that accepts it and that business must, at minimum, exchange it with another currency and so on. Each of these constitutes one transaction fee which multiplies the velocity by, not moving money through financial games but by moving it among the productive economy.
Today's shadow banking system transacts nearly 1000 transactions for each productive one in the real world. This would not fly in a transaction taxed economy yet for any productive member, they're only ever paying the base 1% on any and all their monetary activities.
Also, given the technological unemployment issue rearing it's ugly head, and automation migrating to doing transactions between two autonomous systems, this solves both of those issues with one stone. Each robot/automation system doing a micro-transaction would still pay a micro-fee which still adds to the daily dividend.
I've written up a short paper on it. You can find it at http://usbig.net/papers/McKissick_Bitcoin%20Basic%20Income%20proposal%20copy.pdf
I look forward to any and all criticisms and critiques. It is just one possible way to implement it but I believe it has been refined pretty well.
Looking forward to hearing the feedback!
