the state of cryptocurrency is very difficult to predict

[kevinzxz]

Many people predict that Ripple will be defeated and replaced by Litecoin, but what happened was not as expected, because it was not Litecoin who defeated and replaced Ripple, but Polkadot who had defeated and replaced Ripple and the unexpected is Cardano who immediately defeated and replaced Litecoin, so that makes me believe that in the future Cardano will beat Ripple and make Polkadot a rival.

OMG!!! polkadot has increased 86.46% in the last 7 days, it makes me a little regret, because before I invested in Ethereum I also wanted to invest in Polkadot, but I prefer to invest in Ethereum, because I believe the price of Ethereum can increase higher than the price of Polkadot, but in fact the price of Polkadot has risen higher than Ethereum, although I believe that soon the price of Ethereum will definitely increase very high too, but if I invest in Polkadot at that time, then now I can get a very big profit.

Polkadot is on another level as ETH2.0 is on the way and everyone so much positive that it might be surpassed ETH in the long run. I'm still with Ethereum , but let see what's going to play around. XRP might be back to previous form if SEC issue is solved asap as alt season is already started, imo. TBH, everything is unpredictable as always.

[cabron]

We don't know yet what will happen to XRP though, you can't just conclude.

I have not explored Polkadot but it was said by users to be an eth killer just as most of the token project claiming to be the one that will out rank projects. There were saying that DOT is a copy of Cardano. I dont if there is truth to it but the two will definitely compete in this position.

[Oz Bezarius]

Of all the alts I didn't invest in, it would have to be DOT that rises to the top.

[WalkerIVIV]

It would be good to see that but have you experienced with the old chart of the old coin like LINK and ADA. These coins have ever got the same chart like that and after it reached the peak price and the parabolic trend will be happening. This is seomthing new in crypto because i never see DOT gets pumped before to create a new ATH.
DOT could be back to the below top 4 CMC again in the future. We are still in the bullish trend of DOT.

[Reid]

Oh man, something new. Something fresh.
And I don't even have a clue what Polkadot is.
It may be too late to invest though.
But, it's a good thing to be seen on the frontlines. Just curious though, where was Polkadot ranked before this uptrend?

[Kong Hey Pakboy]

The crypto market is really tough to predict due to its volatility, that only a few people have made a precise prediction and speculation in the crypto market.
Polkadot's ICO project in 2017 is promising that it is one of the ICO projects that survive and last long until this year due to its outstanding innovation. It is why it made it on the top 10 coins in the crypto market that it surpassed several old top coins, and many investors assume that it could replace Ethereum in the future.

Defeated?? Is this word the perfect term to use in this scenario??
You are basing base on the market cap which is wrong.

Now regarding to Polkadot, lucky for those investors who invested to this coin and now they are in a profit as of now. A coin that just came out of nowhere and now at the top 5 already. Quite hilarious I think but it is what it is. Currently top 5 base on market cap, DOT have a good future alongside with Cardano. XRP? I'm currently holding some of it but just for short term profits. Not currently holding LTC as of now.

[poodle63]

I mean, XRP being replaced that's obviously gonna happen after SEC lawsuit but to predict that polkadot turns out to be the one who overtake XRP is kinda surprising. Although polkadot already known as quality coin but it's really such a surprise not to mention how polkadot gets pumped like so fast and now up around 70%.
I would not be surprised if in the next year polkadot replace overtake ethereum market cap if ethereum issue left unresolved, many people seems to favor polkadot right now.

[rainingbitcoins]

for now there is indeed a lot of green on the exchange so now is the right time to sell altcoins or buy them and hold for some time to be profitable. but on the other hand, in my opinion, it won't last for a long time so it might return to normal or it can be pumped even higher.

[GreatArkansas]

I don't think the word "defeated" and "replaced" is suitable words for what you want to mean OP.
Your picture attached from coinmarketcap is showing the highest market cap in cryptocurrencies, which the new player here is the Polkadot and Cardano. These new faces on the top market cap are outperformed Ripple and Litecoin, which is kinda impressive.

[Eco_111]

Lol it's why I don't make move on people's advice in crypto space, I only listen and learn from the advices, the fact is no one have the power to know what is going to happen in crypto space in future or even coming months, that is impossible, sometimes we just have to follow our hearts

[Xardasim]

The ranking cannot be determined in 1 month. I believe we will see more movements in the next days. Notice that the re-increase is more common. Another reason for this is to make a profit, people head to increased coins. And this causes the increasing project value to increase even more and reach somewhere for now, which is not known whether it will be able to protect that place in the future.

[bittick]

Of all the alts I didn't invest in, it would have to be DOT that rises to the top.

The existence of DOT in a good ranking at the moment is because of its good condition and they also really take advantage of XRP's condition, which is in trouble, so that DOT will easily shift it to the bottom rank.

It's just the matter of time until the reversal trend will be happening with the DOT. DOT itself entered the overbought zone and DOT is starting to enter the bearish trend.
People should go out from DOT before it will be dumping again by the whales.
It's not so difficult to predict what will be happening with crypto as long as you are aware about the trend.

[Shallow]

Just like you rightly said, it was anticipated that Litecoin will beat Ripple, but however it turned out to be the other way around, meaning the crypto space can't be predicted, at the same time, saying that Cardano will beat Ripple might still go the other way around and Ripple will continue being above it, and Polkadot on the other hand might drop in rank; all these are speculations as that is all we can do, while the market is always working differently. Therefore, considering all these, I think it is better to leave the market to work and stop predicting, invest in whatever coin you want with good decisions. However, if Ripple is defeated, then there is every tendency the price will dump more and other coins will overtake it, but for now, let's keep our fingers crossed.

Others opinion can be taken as a comparison to the fact. So many people have been spreading BS if ripple will be the future of payment channel system in crypto but the opposite thing was happening after SEC has been suing ripple for the illegal security token offering.
you must also always use your logic and it seems like DOT is the only potential project from the list that mentioned by OP. XRP and ADA will be going out from its top position.

[Kabul]

What the hack, I have never seen this coins before and right now it is placed on the 4th on coinmarketcap rank. Damn, I guess I have missed a lot of opportunity while I was away from the market. Many things have changed and I need to adapt to new situation. I will soon make a research upon this coin.

Cheers to everyone who have earned a great amount of money investing in Polkadot

[Coyster]

People should go out from DOT before it will be dumping again by the whales.

That's the thing with quite a lot of altcoins, they pump and then dump, if I was an investor in the polkadot coin, I'd have sold it already, I don't quite believe in the long term productivity of altcoins, except for just a few, like Ethereum for example. I'm impressed with the said Polkadot coin, and I just hope their devs/team are looking to continue working on theirs system for the long term, cause if not, there could be a final dump waiting to happen.

I would not be surprised if in the next year polkadot replace overtake ethereum market cap if ethereum issue left unresolved, many people seems to favor polkadot right now.

I would be surprised, cause I don't think that can happen, is Polkadot the latest in a long line of coins called the 'ethereum killer'. I do not think Polkadot can get the sort of community of investors that ethereum has, Polkadot should basically just work on their system, as there is surely room for improvement, and we'll see where it takes them in the future.

[DraGonD]

Yes, this is the main feature of crypto. Its incredibly volitile and this the reason why people are here
