I'll second this, make sure to add more coins before running bitcointalk contest/promo although I'm not really sure if there will be many participants. At least I know some people who are willing to risk their money for such contest but they do not want to pay high fees for their deposit.
For now if you guys don’t want to play or be the part of of the promotions by using BTC , then we recommend you guys to use EOS as it has little to no fees and that it’s much quicker and we are also adding ETH, LTC and DOGE by end of the month. Waiting for more positive response on this.
