Cryptocurrency investor Brian Kelly said Monday bitcoin cash is the must-own digital currency of the moment.
On Saturday, bitcoin cash miners met to discuss funding for a bitcoin cash development fund, he told CNBC.
In the fund, miners are "going to take some of the rewards they get from mining and put it in a fund to build stuff on top of bitcoin cash," Kelly said on " Fast Money."
"That's how blockchains gain value," he added. "You're going to be getting more use cases to the extent that usefulness translates into value. That could be a positive for bitcoin cash."
"That's a place I want to buy," said Kelly, who is founder and CEO of BKCM, an investment firm focused on digital currencies.
