Re: Is there a company that can trade cryptocurrency for you and produce profit?
Well as for me I wouldn't advise anybody to give his money to some set of people to trade because they are not different from ponzi scheme. They only promise you a high return but what they do in actual sense is to use another new member money to pay your return on your investment I.e the more new people come in to invest the more money for them, on the long run it will finally crash once they can get more people to sustain the business. So my advise for you is do your own research and buy some portfolio of altcoin by so doing you would have diversify your investment and for sure within 12 month to 18 you will sure get a good return on your investment!!!! 
Even if those companies were not a scam, you'll be going against what bitcoin stands for, the whole point of bitcoins and cryptocurrencies in general is to have control of your money and to not have to rely on anyone else for its protection or its growth if you give your money to someone else expecting you to give you more money in return you go against those principles.
