No other blockchain can beat Ethereum because to date Ethereum is the largest smart contract platform. Ethereum is in a position of its own just like bitcoin. Over the last few years a number of smart contract-based blockchains like ADA, SOL, DOT, LUNA, and many more have tried to kill Ethereum but none have been able to kill or outperform Ethereum until now.

Here many say ethereum and bnb coin are very feasible to invest in the long term I agree, but it would be better if you choose another alcoin for short term investment such as luna coin at this time many underestimate the luna coin because the price is currently going down, I sure coin luna will rise again.

I think now Bitcoin will break through the support at $30,000 and it's not impossible that it will continue to decline but that doesn't mean Bitcoin won't be able to recover. What is happening to the crypto market at the moment can be said that the market is currently entering winter and my advice is to hold it for a long time until the market returns to spring.

I chose Cardano because even though this year is not to the moon but if you look at it as a long term investment I think we are quite reasonable to choose Cardano. You can see how consistent they are in focusing out their roadmap and how they build a stable ecosystem.

personally, when the dip occurs, I convert 50% of the assets I own into BNB. probably a lot of other people are targeting BItcoin, or ethereum, and that's not wrong, in fact it's a pretty much recommended option when the dump happens. however, I also bought some LUNA coins, but not many. It's like an investment where when it's not worth it, it doesn't affect my life.
however, for a dump type like a few days ago, popular coin options are the best. however, I think that it's an opportunity to make more of my BNB assets.

In this case, as far as I am concerned, I would sell and take all my profits because that was the reason for investing in such tokens anyway then wait for the market to reposition and reinvest. sometimes we get greedy and think the price will continue then you eventually hodl and lost, no need for that with most tokens.

I myself am not too brave to make predictions about the best investment coins by looking at current or future conditions, although this is the right time to start because the market is still giving discount prices. there are so many variables that go into the ups and downs of a particular coin/token, but in the end, the market will decide.

The problem is always the pegged asset.

Even USDT it self, have some rumor they're not 100% backup by real money (USD). Some rumor or speculation USDT only have backup by real asset around 50-65% from the total circulation. Also, your USDT asset can be froze by them.

IMO, never hold with a long term for the asset who are not 100% backup by the asset and the audit still unknown + don't trust asset who can frozen you. $LUNA issue make people are worried and not trusted with the word of "stable-coin".

In my opnion we still didn't touch the bottom which could become the turning point from the bearish to the bullish market. I assume we should fall to 23-25k per BTC experiencing lots of fear but without this BTC won't touch 100k in the future.
I remember when ETH price was about $180 and nobody wanted to buy it, but thouse who did made 20-25X. 

Not good time for buying dip, better expect second downhill. Investors should be patient and don't regret buying low since this level can't be dip point.

I would literally wait for the market to stabilize and then make a decision on whether to invest in it or not. I am not too confident in investing in it right now as i think it is overvalued considering the plan is not yet functional yet and there is no timeline when the scaling issues will the sorted. If we have a time period on that aspect then the market could move forward considering the overall market sentiment.

We can't conclude that the bear market is over but the recent downturn in the market has been drastic, we've seen how Luna hit an all-time low of $0.6 in just a few days but I'm concerned if the top coin market also results in the same decline in future.

Binance become a Shit Exchange that support Shit coins like LUNA and ANC

I think the current metaverse project is very good and has a good concept in the future is sandbox, axie and mana
These 3 coins have been captivating since last year, they have had their price significantly increased due to the metaverse hype that is about to emerge.
let alone who buys and sells their land using their coins.
sandbox and axie are also very good metaverse games because they apply play to earn with the metaverse concept.
These 3 coins would make the best in the metaverse in my opinion.

Get massive discounts on Bitcoin and Ethereum. I have no other altcoin options for now. Almost all of the portfolio has been focused on doubling Bitcoin and Ethereum, to be honest the current altcoins are too hard to bounce back. So when we see a correction now people know which one to buy.

None. The ethereum killers are already an old legend that is many years old. In so many years, if it were possible, it would have happened, just as the bitcoin killer would have proven itself long ago, if it existed. But Ethereum holds the lead among smart contracts and is unlikely to be displaced by anyone, especially after the introduction of EIP-1559, which made the asset deflationary and attractive for long-term investing. Other smart contract platforms will also do well, but are unlikely to take the No. 1 spot in this ranking.

Right now, every project, and basically everything Elon Musk touches, turns to gold. There is no doubt that the price of DOGE largely depends on what Musk writes on HIS Twitter account.
I wonder if he will soon write something about the new meme coin www.pussdao.com 

In my opinion, there are some of the best coins that are very safe in cryptocurrencies, including ethereum, binance, solana, terra luna, cardano, and pulkadot, especially now that these coins have experienced a very significant decline if you are still a beginner and want to invest in crypto , then it is better to recommend the coins that I refer, because they have a great chance of being able to bring you big profits in the future.

While waiting to be bullish on Bitcoin, buying some altcoins at low prices is a very good choice and if the target is coins that have potential in the market, I don't think there is a need to do much more research especially if you have done research in the past too on each of the same altcoins.

No one really knows when, 4 months after you post this, and the market is still just go up and downs, not bullish. It will likely go sideways until at least the halving of bitcoins. Except the altcoins can fully independent not affected by bitcoin price, but that things is also unlikely in near future. So, I think everyone should just expect a sideway market for the meaning time. And for the question about eth and btc? I don't think ethereum can catch bitcoin in near future, or even it will never, bitcoin is too strong.
