Promocode to mine XMR for free. MinerGate giveaway

[btc_love]

I mine with MinerGate for 3 months so far, and they've launched a giveaway. They offer to win a free xmr mining promo code for one retweet. Usually, you need to pay 1,5% fee to mine monero.

I still think if I should to take part in this giveaway. I think that 1,5% for mining is not such a big deal, but it would be nice to win this promo code. Also, it would be nice to know if there are other mining giveaways.

There were quite a number of accusations against Minergate that they are stealing (under reporting) the user hash rate, resulting into smaller-than-expected mining rewards.
So it's not really a giveaway that worth advertising.
