I guess this is the result of the current bear market we are in. People that are only interested in BTC for the profit are losing interest because we haven't 10Xed in the past month, they came here for profit, lost their patience and are now leaving. In the background however things have never been more positive, there is great news coming from every place in cryptocurrency and adoption is increasing, but that isn't something people notice, which is why they lose interest. If/when we return to a bullish market it will look like people are interested again and the space is alive again, but in reality it has never been dead.
