We use waves, because we believe in waves
And the price of the wave contract will be several times cheaper than on ETH.
This is very important, because system has transactions with a small amount (up to a dollar for example) and ETH contract will simply cost more than the service itself.

The project won't run on the Ethereum network.

1 - That makes no sense. You can still use a smart contract for the Ether payments and your own system for the BTC payments. The benefit for your investors is that with a smart contract your tokens will be automatically and certainly distributed, while with your approach there is only a promise and nothing else. The whole point of using a smart contract is to avoid the middle man, which is you. You offer a project based on the Ethereum network, yet you don't use the one benefit it provides. That is counter-intuitive and can be interpreted as a possibility to scam.

D_market, how would you explain this?
Changing the terms of the contract after investors have given you their money.

I only invested 10ETH, but I am completely disappointing by the lack of transparency and integrity this project is showing.

for everybody who is thinking about investing in this company here some information which could be of interest.

i checked this ico in detail and under the bottomline several red flags were raised for me, so i decided to not invest.

1. no hardcap limit for contribution phase 2 announced yet (https://dmarketio.slack.com/archives/C65BE4X1T/p1502453544630660).

2. in their slack i got the information, that the tokens are sent to the personal eth wallet after the end of distribution phase 1 which would be at August 21th (https://dmarketio.slack.com/archives/C65BE4X1T/p1502964913000142). in fact they are sent at the end of sales phase 2 (November 2017) (https://dmarketio.slack.com/archives/C65BE4X1T/p1503046448000097). in sale policy 3.7 (https://dmarket.io/assets/documents/DMarket_tokens_sale_policy_EN.pdf) stated again differently. here is stated, that tokens are sent immediately after payment is received.

3. it is possible to contribute with Skins.cash tokens. it was stated on the homepage and in the whitepaper that in phase 1 can only be contributed with btc and eth.

for me 1. is the most important one, but 2+3 shows that the company does not what it says it would do. it's hard to earn trust that way.

I just love, when in bitcointalk thread noobs with 1-2 post pop up and start spreading FUD.  That's a sign of success. 

Guys, with proper effort you can reach Legendary status with your FUD, as icey did on DASH thread.  Keep posting!
