360 days is also a very, very long window to purchase. I imagine the purchase history should be available for everyone to see thus can judge when it's a good time to get in? Obviously why they are front loading the first 5 day window with 20%.
Everything can be changed, yet all the devs are supporting it this way. It's a gambling game for 360 days I will be coming out with more information on this project to expose it.
New FactDevs have no stake in the coin
They just want your funds(ETH), maybe Dan Larimer will drop this project like he did Steem/BitShares then go code for Ethereum with all that ETH. Invest in a coin where the developers have no economic incentive to get it successful? LOL! Rule #1 make sure devs have major economic incentive in whichever project you are investing in, they should make less money from funding and more from the value of their project going up to be legit. I'm just being quiet in their telegram writing down all the facts that are being discussed by the people.
