I think you will need to import your wallet again and select the appropriate Mainnet network you want, and all tokens within the Matic network will display. Also, you can easily use Metamask, in this case, you don't need to import wallet again but you will need to add Matic network to Metamask, and by selecting the right network, all tokens will appear.
In addition, Imtoken can also save that stress, import your wallet to Imtoken and select the network you want, in this case you don't need to add network as it is added already by Imtoken platform, thus you can easily switch from one network to the other.
Lastly, Tokenpocket also works almost same way as Imtoken, download the app, import the wallet and you can view all tokens in that wallet through their right blockchain networks.

The dip in the market nowadays is clearly as a result of fud or what some might even tag manipulations of different forms to force most people to sell while whales buy cheaper. Looking at the market nowadays, every now and then, it is about one ban or the other, or about a country or business stopping crypto services and so on. But amidst all these, one of the surprising thing is that, the market is still striving to be strong, keeps striving to withstand all these bad news, which shows that, the crypto market years ago, is not the crypto market today, that is, what we have today is a market that is more stronger than that of years ago, if not we could have seen more dump.
My own suggestion is, in as much as we don't know how far or how long all these will take to stop, look long term towards those coins whose team are trying, especially DeFi coins because with all these bans, many people will find DeFi coins and Dex more attractive.

According to your post, it is being mined since 2017 and from coinmarketcap, it has been trading with an appreciable trading volume, thus can be classified as low cap coin in my own opinion. However, I would say, before going forward to invest, make sure you understand what you are getting into as this space is unpredictable, although it's good you are considering long term but also make sure you are doing so with funds you can afford.
Another point is, what is the assurance it will grow, when there are top privacy coins already which will overshadow it. Therefore, if you still want to invest after your due diligence, then go ahead but use your spare funds, and also wait for a good entry price.

Yes, there are many blockchains but if you notice, a lot of them must have started on the Ethereum blockchain, however because of how outstanding the Ethereum blockchain is, they are all finding it hard to beat it till date. Starting with ADA blockchain, sometimes it gets congested and one will ask if it is capable of challenging the Ethereum blockchain, even Solana some days ago had issues with their network thus still proving that Ethereum is more effective and efficient than them.
Asking, about Solana, it has proved itself through the massive growth it experienced so far this year alone, and currently a lot of projects are building on it which will lead to more growth. Also, owing to the fact that DeFi and DEX are still coming back gradually, Solana might be the centre of attention soon because it's evident the blockchain is attracting more good projects. Nevertheless, more blockchains are stepping up such as Fantom, and the competition in the coming months will be a good one, which will be good for Solana as it is already leading in that aspect.

Most of the times, people tend to have their own way of investing, such as, many people knows that Bitcoin might be expensive for them to acquire thus they will pay more attention on low cap coins with good use cases, so that they can be able to make good gains which is most of the times converted to Bitcoin or Ethereum; even Ethereum is getting expensive now and most people are using same approach to acquire it.
Nevertheless, before thinking of buying Bitcoin and/or Ethereum you must have good funds and ready to be a long term holder, as that is the best way to make the most out of them, but if funds is limited, then the best way is looking towards low cap coins, buy and hold for long term, you will still make your profits.
However, answering your question, I would say 20% Bitcoin, 20% Ethereum and the rest to other good coins making waves now and with more room for growth such as Solana. For the last question, it is not funny to lose money but you have to understand that first before getting involved with crypto, most people who are upset and always check their portfolio might not have carried out their due diligence.

We can't really tell which will be the next big thing as there are many ideas currently in this space, and all it takes is the right time for it gain attention, and once the attention is there, every other thing is set for that trend.
Nevertheless, NFT is not as hot as it was before, or will I say a lot of other blockchains hardly experienced or partook massively in NFT, only few can be said to have experienced it good enough and that is ADA and Solana.
However, in my own opinion, the next hype might be on what a particular ecosystem is offering, and if a careful look is taken on this space, one can see the level of seriousness going on with many blockchain networks now, Algo, Fantom, Polygon, Avax and list goes on. Many projects are being developed on these blockchains and one can only be patient to see what will happen next.
Lastly, I also think Defi is not yet done, moreover it is the most lasting trend we have seen so far, thus many blockchain platforms can bank on it again to offer their own unique services.

Well, I would say the NFTs had a good trend but nowadays i don't seems to fathom how the trend is going, perhaps the trend or hype is slowing down on a daily basis, and if one is to watch the crypto space now, we can see that a lot of DeFi features and activities seems to be going on, in fact a lot of blockchain platforms are already building massively on DeFi and not only that, a lot of projects on several blockchains are already carrying out developments to offer one Defi services or the other. Therefore, I think I would say that the hype is gradually going back to DeFi and this time around, not just for specific blockchains like Ethereum or Bsc, but for a whole lot of other blockchains like Solana, Avax, Fantom and so on.
Lastly, one thing with trend is that, it is good to join on time and make the best out of it, those who joined NFT on time must have made their gains.

Most times, one cannot really point out the good airdrops from the bad ones, yes most of the times also, good and worthy airdrops asks for little info which could be just wallet address, some might go further to ask for twitter and telegram participation, and where some will be true thus paying afterwards, others will only be a means to grow social media channels.
There are some airdrops that didn't only asked for wallet address, but requested for some sort of tasks on discord and they ended up paying, and some of them, their value was very attractive, a good example is those witnessed on Solana ecosystem such as Cope, Rope and so on.
Even today, most airdrops on Solana requires users or interested people to hold some amount of Cope or Rope, and most times, the airdop ended up being worth it.
Now, I am not trying to say there are no airdrop which asks for few data and pays well, but I think the trend is changing now. Another example is, a lot of people know about dydx airdrop, where users were asked to trade, the qualified participants ended up with a very valuable token, listed on top exchanges and still maintaining a good price today. Avax ecosystem also experienced theirs, therefore, like I said, the trend is changing and one can only follow with it, you never can tell what will happen along the way.

If we can remember the potential of BSC network on the onset or the attention it gathered on the onset, then we can understand that same case scenario is likely to play out with Polygon. Let's go this way, BSC was the centre of attention because of low gas fee, in fact a lot of people said many things about ETH due to high gas fee, but gradually the BSC network gas fee is increasing and no one is saying anything again.
A lot of blockchain networks are now being developed of which many of them leverages the feature of low fee to stand and one of them is Polygon. Now the reason I believe Polygon will rival BSC is because, Polygon gas fee is very cheap and the transaction very fast, thus the Polygon network will bank on this for the time being to develop and grow, in addition the team are very serious with what they are working on hence keeping Polygon on a better chance of lasting and/or beating BSC.
Moreover today, many projects are already on the Polygon network while some are migrating from ETH and/or BSC to Polygon.

When the EIP-1559 was launched through the London hard fork, it was seen that, the main aim of it, is to make Ethereum to have deflationary feature such that, on every transaction taking place, ETH is being burnt thus removing or reducing the circulating supply of ETH; this was confirmed on the first day the London hard fork took place and still working till today.
Therefore, looking at this, in my own opinion, it is very evident that, the EIP-1559 have no business with the gas fee, the high gas fee is caused by the increasing number of projects on the Ethereum network as well as the increasing price of ETH. Lastly, the anticipated ETH upgrade is believed to take care of this.

Is that the only exchange that token is listed on, if yes then the team are not really ready to work neither are they ready to grow the price of their token as they claimed. What you should know is that, the project team can never talk down or say something bad about their project, they will always look for a way to encourage users as well as convince them they are working and token price will pump, but most of the times, team that do such hardly keep to their promises. On the other hand, most project team pays more attention on their products and services, looking for more ways to make it attractive because they know, that is what is capable of making their token valuable.
However in my own opinion, before investing in such token and following what the team are saying, do invest with what you can afford to lose, because yobit is not really a good exchange, in fact it's been a long time I heard about anything about it.

Even most experts can't answer this question because fud is one big factor that affects the market while causing market dump, as we have seen today. Yes the market is in blood and no one knows what will happen tomorrow, but if one want to buy into any altcoin, first thing is to make sure that such altcoin is one with great use case such that it will recover and last long term no matter how hard the market dumps. Secondly, if one also want to buy in, and after due diligence finds a particular coin worthwhile, it is wise buying at intervals, such that if the market dumps more, you add to your bag until you are satisfied, this approach helps users to accumulate their desired altcoins.

China is one of the major countries with power thus the reason most of these fuds affects the market even till today. But one of the funny things about China bans is that, since time immemorial they have been banning Bitcoin or cryptocurrencies, and till date they are still banning it, that is to say, all these are just fuds to manipulate the market because for them to keep coming up with news like this means their citizens are still very much involved with crypto and everything that concerns it.
Also, I came across a twitter post where it was said that, the ban was made since 15th and the news only appeared today, if such is right, it is enough reason to know that all these are just manipulation to shake off weak hands.
This is crypto where volatility is high and where opportunities are boundless, thus one need to make good decisions and hold on to coins that are worth it while paying little to no attention to all these fuds.

If you are new to crypto, then I think the first thing that ought to bother you should be how to understand how the crypto space works and the underlying risks, this will go a long way in shaping your mind and intellect towards either investing the right way or trading the right way, since fundamental analysis is also one of the key things to focus on while trading.
So first thing first, know how to research on projects, how to follow up with the crypto space and news related matters especially, else the market might dump on you; this will take us back to understanding how this space works.
Lastly, before knowing what good ways to trade, you will need to learn how to trade else you will end up with terrible losses, and through learning how to trade you will learn more about all the trading tools and/or indicators used in trading.

You are using such thoughts to cheer yourself up, well it is good to fantasies but don't allow it to get ahead of you because, you might be disappointed in a big way. Most of these shitcoins that are abandoned or that are dead is best to be forgotten than expecting anything good from them, let me ask who will launch the market and provide the necessary liquidity, and even if such happens, there is every chance they will exit scam again.
From another angle, such shitcoins might not even see the light of the day because people are not yet done with genuine and impacting coins, not to talk of going for shitcoins that were known to be dead.
Lastly, crypto can surprise that we are sure of, but don't raise your hopes high on those abandoned coins and tokens.

NFT is a trend and just like other trends, it will get to a point that the interest will slow down and once another trend starts coming up, people will leave it for another. Also, it depends on the lasting impression and impact the NFT had in the crypto space, that is, if it is a very lucrative and good one, it will still be around although won't be much but people will also feel it's presence; a good example of this is the DeFi trend which is still very much around till today.
Lastly, many NFT platforms are coming up and now the hype looks like it is going down, you ought to be careful because a lot of scammers will launch theirs in order to make due of what's left. In addition, the best way to benefit from any trend is to join as early as possible.

As of today, it looks more like the market is recovering well, but we have to lookout for daily closing to know our stand. However, one of the things I have come to understand about the current market is that, it is quite different than it was last year or years ago, that is, although fud can bring down the price or dump the market, the way it recovers nonetheless is something interesting. And because of that, those who panic to sell most of the times finds it hard to get in, and where some ends up buying higher, others gets left out.
Therefore, in my own opinion, have a long term bag and set a target, but make sure the coins or tokens are worth it and have what it takes to last long term, with this, you will hardly jump around the market when it dumps but might even add to your bag.

If you talk about trends, then you need to pay more attention to the crypto space starting with twitter, you can start by following top projects, developers and even Influencers but be careful with especially Influencers. Trends in crypto is best utilized when one joins early, and just like NFT that is currently trending now, those who were fast enough to get involved at the early stage benefited a lot.
Now, from current trends you will be able to get into early coins, this is because many blockchain networks will bank on that current trend and developers will look out for ideas to build on, taking the NFT as an example too, I think ADA ecosystem started it first and gradually Solana picked up the pace and today a lot of these projects are growing on Solana blockchain, and where some are new tokens others happened to be old tokens which looked for ways to tap into what NFT offers.
So in other words, try as much as you can to get hold of any crypto trend, join on time and grow with it, the more it goes on the more you grow in more knowledge of it, thus making the most out of it while benefiting hugely.

First and foremost, to build a crypto portfolio might not really have a season or time, although bear market gives more better chances to start cheap. However, you can still take your time to lookout for those low cap coins with good use case and every other thing, keep them in your tabs and wait for a better time to buy; one thing that is certain is, don't chase after a moving coin however be patient with it and you will get a good entry. To add to this, most people might prefer to wait till bear market to buy, and when it comes they will keep waiting while thinking the market will dump more and at the end are left out.
Lastly, bear market like that of 2018 will be hard to come by or experienced, my reason is, the level of adoption today with that of 2018 is quite different and the gap between them is huge, nowadays we keep hearing of many organisations and platforms adopting crypto, we keep seeing many innovations taking place, all these points to a growing market and a growing market like crypto will have it ups and downs but won't get bad like that of previous years.

The answer to your question is very simple; the same reason why a lot of projects are leveraging BSC network because of high gas fees in Ethereum, is the same reason a lot projects are leveraging Polygon network now because of the increasing transaction fee of BSC network. BSC network gas fee is gradually increasing and congestion gradually coming up as well, and since Polygon offers a more cheaper transactions fee with better speed and currently no congestion, a lot of projects are moving to it. And as time goes on, a tougher competition will grow up between BSC and Polygon, at the same time, if Polygon team gets all their works and features right, the same attention and growth which BSC network witnessed and enjoyed months ago might take place within Polygon (but this is just my speculation as other blockchain networks are not relenting like Fantom).
Lastly, most projects are also migrating to different blockchains without any tangible reason other than to pump their token price.
