I don't see how it looks like dying.
Ok, but why doesn't the price rise then? Few people believe in the future of the project? This is also a definite indicator, isn't it. If investors believed in ltc, they would buy it and hold, which would lead to their further growth. But we don't see this. The price was unable to renew even the previous maximum.
It needs a powerful hype to do that. LTC is a calm crypto.
