[Q]: 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Since Attorney General Jeff Sessions rescinded the Cole Memo  sending pot stocks tumbling  there is reason to be concerned when dealing big money in marijuana.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.

[Q]: Venezuela's  President Nicolas Maduro (C)  speaks during an event related to the Sowing Plan "North Summer 2017" in Araure  Venezuela September 27  2017. Miraflores Palace/Handout via REUTERS ATTENTION EDITORS - THIS PICTURE WAS PROVIDED BY A THIRD PARTY
CARACAS (Reuters) - Venezuela âs President Nicolas Maduro  railed at two of  his  main international critics on Wednesday  chiding Spanish Prime Minister Mariano Rajoy for âmeddlingâ and mocking U.S. President Donald Trump for geographical ignorance.
The United States has recently imposed sanctions on Venezuelan officials and Spain is pressing for the European Union to follow suit as international pressure grows on  Maduro  over  his  record on human rights and democracy.
âWhy is the global right wing so obsessed with our homeland?â  leftist Maduro  responded in an address on state TV.
Lampooning âlittle Marianoâ for mispronouncing his name âMaderoâ   Maduro  said  the conservative leader  should focus instead on Spainâs internal problems  Cataloniaâs independence push  and Europeâs problematic relations with Washington.
âForget talking about Venezuela  which is a homeland of dignity â  Maduro  said. âI reject and repudiate Mariano Rajoyâs meddling  rude  absurd comments against Venezuela.â
 Maduro  faces global criticism that  he  has turned Venezuela into a dictatorship with the creation of an all-powerful Constituent Assembly  jailing of political opponents and quashing of protests this year in which 125 people died.
Having in recent days labeled Trump a âHitlerâ and âimperial emperorâ supporting violent coup-plotters in Venezuela   Maduro  took aim this time at the Republicanâs intellect.

 Maduro  repeatedly calls opposition leaders pawns of the United States intent on toppling  him  by force.  He  says the Constituent Assembly  elected in August in a vote boycotted by the opposition and condemned by various foreign powers  has brought peace to the nation of 30 million.

[Q]: But  U.S. Ambassador to the United Nations Nikki Haley  expressed confidence the transfers could be blamed on Tehran.
“These are Iranian made  these are Iranian sent  and these were Iranian given ”  Haley  told a news conference at a military hangar at Joint Base Anacostia-Bolling  just outside Washington.
The unprecedented presentation - which  Haley  said involved intelligence that had to be declassified - is part of President Donald Trump’s new Iran policy  which promises a harder line toward Tehran. That would appear to include a new diplomatic initiative.
“You will see us build a coalition to really push back against Iran and what they’re doing ”  Haley  said  standing in front of what  she  said were the remnants of the Nov. 4 missile.
