I find it much more effective than gambling with fiat.
Thanks!

When you say much more effective, can you a little bit elaborate on that term. Gambling is a 50 - 50 trial, and for those who has been in the system and knows how it works, they know the little tricks and stuff that are in the process. For me am not a gambler, but wanting to see how that part looks like in the crypto community, but one thing I now for sure is that it is not as simple as one may think it is. If you are not good at predicting games (sports) or the casino and those stuff, you'll end up just going round.

As a believer that dogecoin will still go high again, there is a factor that I came to see that dogecoin on a yearly basis, a high amount of dogecoin of about 5 million is being pumped into the market yearly, and because it does not have a specific total supply (it's like pouring water into an endless hole), the coin will continue to find difficulties in reaching or attaining good price mark in the market. I hope the price of dogecoin someday somehow will get to the price of $1 mark as an ATH.

The future of dogecoin is bright, though for now the deep has made it look as if it experienced a price bubble and  the bubble has popped, but that is not really true, it has for now created awareness to the entire crypto verse and the market experienced it's move. Elon Musk who is the acclaimed doge-father who is the doge influencer, making it more popular with attention drawn to it. The issue dogecoin will stay to face is the ever increasing quantity of dogecoin on yearly basis. The introduction of 5 million dogecoin into the market every year will make the price not go viral in price, but will make people rich if it should get to $1.
In summary, the future of dogecoin is bright for long term investment (because of Elon Musk).

I don't really see the possibility of litecoin taking over Binance or Etherium, that is just way too high for litecoin. Binance has an exchange with lots of users adopting the use of the Binance native coin BNB, the price is rapidly  increasing, holding strong the 3rd position in coinmarketcap. Etherium is on the back to back chase of Bitcoin, having strong believers and supporters, holding the 2nd position.
Charlie Lee, founder of litecoin who sold all his coins, it simply means he has no interest of working or making development on the coin.

There are currently many coins in cryptocurrency, including light coins and binance coins. But now Binance Coin is take very good position than litecoin. Can you think litecoin  also overtake binance.

I don't really think litecoin can overtake binance coin. Binance coin BNB is a coin that will stand to keep on existing so long as the binance exchange is also in existence. Not all coins we will use for comparison, litecoin in its own form has it's uniqueness, like the proff-of-work, four times faster block creation with an average interval of 2.5 minutes. BNB has gained it's supporters, users and has a trading platform which is one of the biggest exchange in the whole crypto space, having its own native coin BNB.
It is true that litecoin has been in the system for years, but consistent development and improvement, with marketing strategy also have a way of improving products.

The push and energy of doge coin to reach $1 is very very possible, it might take a while, but it's very possible, and that could be even before the year 2022 runs out or so. But for it to get to the highs of $10 per doge coin,  , It's hard to say it's impossible, but that will take forever for it to happen. Every year 5 billion coins are being pumped in as incentives, that is ($5billion * $10). No, if doge goes so high, $5 will probably be it's mark.

Doge so far has gained more popularity over the years, and survived the market challenges, though it has been a coin that has come a long way just that it has not really made a huge impact in terms of its price. Doge coin which is based on litecoin, and uses the same proff-of-work network can still make a difference even as time goes on. One thing about doge coin which is for sure is that it can not go very high in its price ($1, $1.5 is possible, but will hardly get up to $5) as it has an unlimited total supply. This will continue to affect the price, but it's popularity will definitely continue to grow as it has a big supporter Elon Musk which truly has drawn attention to this coin.
