I have recently signed up on the trust(lol)coin exchange because someone here was saying there was a promocode for a few free satoshis, I redeemed the code and tried to withdraw, it said I had to play atleast one roulette game before i can, which is what I did, and it said I had to deposit 0.016 to prevent abuse from the promo code. This is obviously a Scam!
Be carefull Newbies! don't fall for this crap!
I would not recommend for any trade or any thing with new exchanges. Because it's too much risky for any kinda deal with new exchanges. I also faced some problems couple times when i was trying to sold my coin.
Now days joining in giveaway is really risky task. If you are not careful much scammers will loot you for sure. The simple thing is no one will give you free money, if some one try to give you unrealistic offer then it's better to stay away from it.
