Buy altcoin at lowest price and sell it after a week with nice profit 
Just check all altcoins in the market 
what if he does not have knowledge about trading, he'll lose if one chose altcoins, and certainly not easily see all altcoins Just check all altcoins in the market That`s why i pointed out btcinvestment for him its hands off and works great
Me to have made the big mistake to buy altcoins in the start whit 0 knowledge. it delivered me -11 btc in 6 months.
Now i don`t have to do anything except transferring my btc to btcinvestment.
best part is they are not trading crappy alt coins but real stocks, forex anything you like.
if the site is suddenly scam,? you certainly will lose all your bitcoin
