I don't trust coins that are closed source it can only means you don't have control in your coins and if they don't have a desktop coin where you own your private key and wallet.dat,then this coin is useless and the dev of the coin can confiscate your coin anytime.
Yes, it is like centralization of coin even more dangerous than fiat money, all of the coins be controled by developers,
i am doubt about this coin will be successful because it can be manipulated by developers and other people who has big money, but it is just opinions i hope there are developers of coin on here and can make clarification about it.
