I think part of the reason for the decline in interest is the fact that the whole system about the cryptocoin aspect of TILT is unnecessarily complex.
You have an ETH clone chain, which is not much use since everyone has the incentive to hold in the poker-room
And you have another chain in which people must convert their tilt to a derivative toket, to exchange for other derivative tokens, to then be exchanged for proper tokens... if anyone is found to actually buy.
And all this still has to be manual by you for the conversions.
Even experienced crypto users will get confused and discouraged by all this.
It just begs the question, why you wouldn't go for some tried and true method like the following:
All you really need is a bitcoin clone (easily supported by any exchange), full PoS with small reward just to keep the chain going
Then give everyone in the room a deposit address to put TILT in the room and allow also withdrawal functionality to any chosen address.
Then it can be handled easily with scripts or whatever to make all these deposits and withdrawal automatic.
Everyone will be happy then and I'm sure the tilt token would have value.
This is not criticism, so please don't take it like that. I'm simply puzzled by this apparently useless complexity and curious what you think.
