AFAIK until now hodling for long term usually pays off and you just need to wait until another bullrun season and you gonna get big profit but the hardest thing is the price movement that sometimes affects us emotionally to make such bad decision as such is selling.
Most of the coins that I've seen in the past having low valuation now already multiples its former price, not to mention if we do staking aswell which increases our token holding.

Their capital is indeed very high but if I doubt they got this far just because of they have the capital, to just pump and wastes billions of dollars seem doesn't make sense to me unless they could influence people into following the bullrun just like how elon could hype up dogecoins. After all binance influence already covers every corner of crypto.   

If it confronts many of the governments interests across the world then a big chance the government will try to crack down these kind of coin. I will be honest, government hates these kind of coins that are totally out of their control and it probably won't become a global trend.

It's just hard you know fighting against the government and not to mention many exchanges have started delisting some of the privacy coins.

The problem is such pump that happens after we sell is totally out of our control, you just can't know whether the coin will go beyond the price when you were selling or instead dumping and trading plan honestly have a very little to do with it except you want to spread your sell order across many price point then maybe that could minimize the risk of selling to early.

You know everytime elon trying to hype up doge some people lost money in flash pump and that means its gonna drive down the hype when he make a tweet regarding doge once more. I doubt it's gonna make doge goes beyond $1 not to mention every doge added to total supply every blocks mined, overtime making doge to $1 gonna take a lot of effort and that increases linearly.

At most polka might just become an alternative to ETH and not replace it entirely, the competition for top crypto is really tough and as you've seen despite BNB having its own momentum and performs really good they still sometimes gets taken over by other altcoin let alone killing ETH.
It seems the #1 and #2 position almost always belong to BTC and ETH tbh, the gaps of market cap too wide.

If you're not so sure then simply just wait for another correction and in every bearish or market correction is a good time to invest since you got it cheaper but it all depends whether you want to hold or not if the price happens to go further down.
What makes you earn profit is how you can manage when to sell or buy and control your psychology, even if people buy in ATH they could get a profit if they hold it long enough until it hits new ATH.

Now the fee is 100 gwei per gas which is quite "cheap" if compared to when the network traffic is on its peak but honestly it's far higher than other blockchain.
But to be honest, we here have no time of waiting ETH to increase its TPS and many people will try to find alternative to ETH but it's not gonna make people leave ETH because if they did, the fee will also decrease meaning the problem gone.

Not only telegram but almost all of the popular platform there gonna be some scammers. even twitter right now is full of so many scammers and youtube too with all the fake conversation about fund manager created by some bots. Best course of action is just to report them so other people who are lacking in information regarding the scamming activities might never see it because the scams gonna be deleted immediately.

I know everything is possible in crypto market like how BNB could suddenly go up and take the third position but honestly you should take his statement with grain of salt, he's a businessmen and taking financial advice from businessman who seek profit with a product in my opinion is not really right. I'd just consider this one statement of him as just a joke because i'd only believe BNB could overtake ETH if their market cap is half as big as ETH's

Exactly what i keep on saying, it's gonna be different than the usual cycle and $45K above is the new bitcoin's "normal" price. Many people think it's gonna be like before and there gonna be massive dump bla bla bla but turns out we could still go up again and retain the price near ATH.
People should know that the effect of large corporation and institutional investors really huge to the market.

There's still no obvious clue of any altconi could overtake Ethereum considering the gap of market cap between the coin but if I'm guess I'd definitely think of any other smart contract altcoins that did the same just like ETH but have their own quirk like maybe BNB though binance actively burning BNB coins so I think it's gonna be hard for them.
Other than that Cardano or Polkadot, these two are the most logical choice as of now to be honest.

Bitcoin halving was hardcoded and surely will happen, however bullrun on the other hand could happen when halving occurs or not. If you're asking about the correlation of halving and bullrun I think it's because that sense of scarcity you got everytime halving occurs which means block reward for the miners decreases.
Most of people also expecting the price go up due to that sense of scarcity and when all people expecting the same thing and adds demand to the market, the bullrun happens. just my 2 cents though.

All the people should know that following some billionaire advice regarding crypto is gonna be a zero sum game, the money that helps the pumping coming from individuals pocket and the market easily shaken by the panic sellers that it's like a gamble, not to mention many effort from people out there trying to impersonate the figure and making some hype.

They're the same thing, what makes them different is just how much exchange they were listed on therefore makes it really convenient to trade if they're listed on various exchanges of your choice. Other than that maybe who's behind that stablecoin but honestly doesn't matter that much as long as you used it temporarily not for hodling too long.
I'm myself prefer USDT just because I've used it since long time.

Just use tron if you just trying to send some stablecoins they are quite fast and cheap at the current moment, atleast if compared to other popular coins, but coin that's placed below top 10 on coin marketcap usually have really cheap transaction fee but just remember to choose coin that has been listed on many exchange just for the sake of convenience.

People try to create duplicate or fake accounts so rampant nowadays, it's not a rare sighting for us to find these fake accounts swarming some popular figure's tweets and projects.
That's why you should double check everything that you trying to do in crypto space. Heck, everytime I pasted an address I'd check it like 5 times because i'm aware the existence of malware that replace address within clipboard.

Honestly elon's tweet won't have the same effect anymore, many people losing in doge flash pump, and they won't participate the hype again, sure there will be bull run again but maybe won't be as spectacular as it was when Elon first tweeted about doge, people already moving on and switching to BTC because it feels more legit following institutional investors.

You mean some sort of puzzle? There are plenty of puzzle created that got some private key hidden but whether or not satosh nakamoto hide some private key in forum or something else none of us could really answer that, but tbh maybe there is, but we don't know that it exist because it hasn't  discovered yet or there's nothing like that at all.

People with common sense should already know from the very start that doge, as its own name itself explains a lot is a meme coin and not really good for long term except swing trade, it's crazy to expect a coin with such total supply to go about $1 and even in the future thats not gonna happen because the uncapped total supply doesn't allow.
