peerplays was always and is still overvalued (I think marketcap is 20-30 million or even more lol, edge is still under 1 million. this also means 20 times less pay outs to investors compared to edgeless). by the way they are not using smart contracts and ethereum...they are using old tech...they are very slow in dev and did not reach there goals in time....they dont have a great team like edge with real gambling and smart contract experts....strategy is and was never clear, first they announced normal online games, then gambling, maybe because there is more money but also more competetion lol...there are even more to say but I will stop now.
Investing in ICO these days is a gamble. You never know what will happen. Edgeless so far has raised around $1 million, it could be 5x more after launch and realization of the roadmap or it can become 5x less if dev does not deliver or gets delays.
Of course, you know not ICO, buy and sell an altcoin or even bitcoin is a gamble, you target to profit, but sometimes you lost the money. But edgeless is different, we can profit from casino profit, IMO it is guaranteed, we need noob blackjack players.

Yes, rich noob blackjack players are needed to sustain zero edge.
As to the profits, you will still need some luck as a huge percentage of it is distributed thru lottery.
