This coin is very similar to Beam. The same technology, often their price should be synchronous. Beam is already on Binance. Not waiting, but preparing.

Which do you prefer, beam or grin?

There are some differences between Grin and Beam.
The first Mimblewimble technology was invented by Grin. Besides, Grin doesn't have a management team. Most of the employees are volunteers. Beam is led by a team.
I think a project called Epiccash recently created a project using mimblewimble technology, I think it's worth a look.
