Don't invest in something just because of hype, not unless you understand the risks.

Look at the positive side, both LTC and XMR have a strong community. That's what matters. There's no such thing as fading hype there.

Besides, the whole crypto industry in general is volatile from the beginning. Will you play instead on new tokens out there, which increase the risks and are more speculative, instead of keeping up with the momentum of those coins that have already been tested during the bull and bear run?
