Cryptocurrency ETFs  proved too risky for ETF Managers Group Founder and  CEO Sam Masucci   but  he  threw caution to the wind with  his  latest marijuana ETF â and it's paying off.
"The business is growing  the companies entering it are growing "  Masucci  said on CNBC's "Fast Money."
ETF Managers Group in late December launched Alternative Harvest ETF  which tracks around 30 domestic and international stocks that may benefit from the growing marijuana industry. The ETF started with $5 million in assets under management and has grown to around $400 million in just under a month   Masucci  said.
Since Attorney General Jeff Sessions rescinded the Cole Memo  sending pot stocks tumbling  there is reason to be concerned when dealing big money in marijuana. But  Masucci  has accepted a degree of volatility  something  he  wasn't willing to do with cryptocurrency.
"We can't explain the volatility within bitcoin. Until we are comfortable with it and we know how to trade it  we don't see ourselves getting involved "  he  said.
A majority of Alternative Harvest's companies are based in Canada or other countries  where legalization is impending or where regulations are more lax. As far as domestic companies go   Masucci  said ETF Managers Group was careful to pick those best suited to benefit from the cannabis boom  like hydroponics company Scott's Miracle Gro or cigarette manufacturer Philip Morris.
"We will continue to participate in those companies that are largest  and right now  the largest piece is outside of the U.S.  " Masucci  said.
Despite Sessions' actions   Masucci  has high hopes that the U.S. cannabis industry will stick around.
"Twenty-eight states now have approved medical marijuana  16 more have it on the docket for this year  " Masucci  said.

American Sage Kotsenburg won gold in the event at the Sochi Games in 2014. We brought him into the âOlympics Cornerâ today for his thoughts on how to watch. Keep scrolling to read that Q&A.
Throughout the Games  weâll occasionally bring someone in to help us better understand the Olympics. Today:  Sage Kotsenburg .
Four years ago in Sochi   Sage Kotsenburg  shocked the snowboarding world by winning slopestyle gold.  He  followed that up with what President Barack Obama told  him  was the âchillestâ interview of the Olympics.  Kotsenburg  has since stopped competing  so  he  wonât be in PyeongChang. But The Post caught up with  him  by phone during a recent film shoot in Italy to get  his  thoughts on this yearâs slopestyle event (8 p.m. Eastern time Saturday on NBCSN).
A: Three people that I would look for are an American kid  Red Gerard.  He âs absolutely crushing it right now. This course  when I saw it  I immediately thought Red can really do well here. I wouldnât be surprised to see  him  on the podium  if not up in the top five.
And then Mark McMorris  who got bronze last time around.  He  came back from a really  really bad injury  so Iâd like to see  him  do good  too. Weâve been good friends for a long time.  He âs crushing it  too.  He âs doing a really  really  really good job right now. Iâd like to see  him  up there.
Iâll give a prediction for gold: Itâs going to be Marcus Kleveland.  He âs from Norway.  He  has pretty much anything you want in a slopestyle course and more. So  if  he  puts down  his  run   he âll probably win or silver  Iâd guess.

(CNN)  Irish Prime Minister Leo Varadkar  has said  he  aspires to a united Ireland based on "cross-community support" in remarks released on Tuesday  the UK Press Association reported.
"In terms of a united Ireland  our constitution is clear on this "  he  said. "Our constitution aspires to there being a united Ireland. I share that aspiration."
But  Varadkar  made clear that unity between Ireland and Northern Ireland -- which is part of the United Kingdom -- could come about only "by consent."
"When it does come about I would like to see it command a degree of cross-community support "  he  added.
Building support for Irish unity across both Catholic and Protestant communities in Northern Ireland is "a 50-year project " Bew said.  Varadkar 's remarks are "a way of saying ... we don't want unity any time soon."
Whatever his motivation   Varadkar  is likely to come under renewed fire from pro-unionist parties in Northern Ireland.
In the days before the border deal was brokered   Varadkar  and  his  government were accused of exploiting the negotiations to forward their ambitions for a united Ireland.  Varadkar  was insisting that talks should not progress until London committed to preventing a "hard" border.
