For sure? if it was so easy everyone would be rich.
I don't really see Litecoin any better than Bitcoin (the king), Ether (Dapps, Defi, etc), Link (Chainlink) or even Stellar (for payments). Litecoin is pure speculation in this moment. Why someone would use Litecoin for payments when there are better alternatives, and why it would be used as store of value when there's Bitcoin?
The reason Litecoin hit ATH in 2017 is because all coins hit ATH back then. But times changed and I have seen very little progress with this coin.
(I own Litecoin btw, but I don't plan to buy more)
While Litecoin is no better than Bitcoin and most other altcoins out there on the market, it's still one of the oldest and most trusted cryptocurrencies in existence today. This allows Litecoin to have better branding & mainstream recognition than other newer altcoins being used by people in the mainstream world. The mere fact that Litecoin's supply is limited (only 84m coins will ever be mined) tells us that sooner or later, it will rise towards astronomical levels in price. Of course, there needs to be active development and innovation to sustain these claims. With the announcement (and hopeful integration) of Mimblewimble into Litecoin, things could start moving in the right direction. Until then, Litecoin will remain stagnant in price across the crypto market.
As a long time Litecoin hodler, I still have faith in the cryptocurrency (despite not showing any signs of demand at the moment). After all, Litecoin is a tried-and-tested cryptocurrency that resembles Bitcoin in every way. Other altcoins have lesser security than Litecoin being easily prone to 51% attacks. With good effort from the LTC community, we could experience new gains across the crypto market within a couple of years from now. It wouldn't hurt saving a few coins just in case the next bull market has a positive effect over Litecoin's price.
Nonetheless, there are many actively developed and maintained cryptocurrencies out there which prove to be more popular than Litecoin itself. This would challenge Litecoin's place on the crypto market within the long term, if it doesn't gather the attention from people in the mainstream world. It's up to Litecoin supporters to increase mainstream adoption for their cryptocurrency, in order to maintain its price for years to come. Otherwise, Litecoin could end up being just like Dogecoin as a purely speculative asset. Just my thoughts
