Don't forget about the bear market, in the next 5 years we will at least get past the bear market two to three years before going back to the bull market again. You may be able to take the last moments of this bull market, but only temporarily and make sure after that you exit the market to avoid the bear market,
I personally have made a map for the next 4 years calculated after 2021 ends, The first 2 years was a bear market, and the next 2 years was a bull market.

That is an interesting fact, but don't focus on the quantity of coins, because quantity is very different from quality, you better focus on the technology that the coin has, even though there are already many tokens or coins but it is possible that there will be new coins that have better technology than old coins. For example MATIC and ONE have better technology than old coins like NXT or VTC

Energy consumption is just an issue created by Elon Musk to manipulate market, don't you know how much electricity consumption Tesla electric cars use??? Elon Musk owns an electric car company that could threaten even bigger electricity consumption than Bitcoin, but strangely that's not an issue lol, ,

I will give one simple reason so that you are not confused about which coins are good and which are not, look for coins that use PoS consensus, and avoid coins that use PoW consensus, then you will know which coins consume electricity, examples of coins that use consensus PoS is Cardano.

XRP is not a shitcoin lol, when compared to TRON, XRP is still quite far ahead, you can compare it by looking at XRP ranking in market capitalization, now it is still ranked 6th even though the price movement is slow, and TRON is now ranked 25th.
This proves that XRP still has more fans than TRON, although if I'm honest TRON ecosystem is better than XRP.
Actually a big correction is not a problem for XRP only, because all altcoins will also correct when Bitcoin is corrected, so I don't think this is a big problem.

Sushiswap is one of the best DEX, no need to hesitate if you want to invest there,
I will give you a list of the best DEX, so you don't get confused when choosing them, because there are so many DEX,
ERC20 Network : Uniswap, Sushiswap
BEP20 Network (BSC) : Pancakeswap, Bakeswap
those are 4 famous DEX, and you should not hesitate to invest there, especially Sushiswap.

I agree with your opinion about Bitcoin, but I don't agree with your statement "how strategic bitcoin is to every altcoin out there", because this is not about strategic Bitcoin, but about correlation between Bitcoin and Altcoins,
If Altcoins are still connected to Bitcoin and cannot stand alone, this means that there is no possibility of an Altcoin that can replace Bitcoin, because one of the ways Altcoins can replace Bitcoin is by being independent of Bitcoin, especially not following the price of Bitcoin when it goes down or up.

Coindesk and Cointelegraph are the best cryptocurrency news sites and the news provided is always new with clear evidence that it is not a hoax.
There are some recommendations from me, but I can't guarantee it will be better than the two sites, but at least enough to be a reference, the sites I mean Cryptocrunchapp and NewsBitcoinCom, sometimes I also look at Coinmarketcal, indeed this is a site for events, but very helps to find the latest information about what will be and is being developed

In my opinion full concentration is not facts about trading, but understanding of risk management, knowledge of trading and also experience is a must have,
there is one way to do these three things, by understanding your own potential and determining the Time Frame to use.
when you have done that, full concentration is actually not needed, because trading is not about shooting animals in the forest, but about anticipating every market movement.

It's not just about not learning from previous mistakes, but about the strategy used as well, because it's really hard to predict a good coin, especially a coin that still has a small market cap.
Many people prefer coins that have a small market cap because they have a great potential for their price to rise higher.
and I think this is reasonable, because sometimes coins that have large market cap move slowly in price, for example TRON or ONT, ,
So, instead of spending time on slow moving coins, it's better to look for coins that have a small market cap but have good technology and big potential,
it's just that it's very difficult to find coins like this , , even though i have learned from previous mistakes , ,

Don't say maybe, we are not memecoin mania lol, someone will become memecoin mania when already invested in it, and unfortunately if we look at the facts, only beginners like memecoin.
Like Dogecoin, I don't invest in it and never buy it at all even though the hype is very high, I'm sure a lot of old players are like me because memecoin is just a coin for fun not for long term investment.
Memecoin will be the same as the trend in previous cryptocurrencies such as ICO or Privacycoin trend, only some will survive and others will become scams because they are abandoned by developers.

Long journey? Nothing is difficult for Dogecoin when Elon Musk still supports it, because what made Dogecoin run to this day is Elon Musk, so as long as Elon Musk is around, nothing is impossible for Dogecoin, and look at the fact again that Dogecoin has been accepted on many major platforms like Coinbase Merchant.
And if we look at today's bullish market conditions, then Dogecoin's journey to $1 is very close and it's possible that Dogecoin's price will touch $2 or $3 when the bull market reaches its peak.

NFT is something interesting, I personally only follow in blockchain based games that use NFT,
If you need a recommendation, I can recommend game "X World Game (XWG)", the item is quite cheap and uses the BSC network, so the transaction fee is also low, I've been playing for a few weeks and it's quite interesting, because we can stake our NFT in the game and get tokens that can be sold on PancakeSwap , , ,

TRC20 is a token that has low transaction fees, I'm sure many people will invest in TRC20 tokens because there are so many coins that have a wrap version on the TRC20 network,
I personally only invest in TRON, BTT and WIN tokens, these three coins have unique and advantages, such as TRON which is the core of the TRC20 network, BTT with web browser and WIN with Oracle and of course the gambling site , gambling is not a good habit, but a lot of people like that, so I think WIN is one worth holding on to long term.

Everyone has considerations to sell the coins they hold, the price increases very high due to market demand, so actually there is no limit the coin has finished its golden age, Doge and BTT still have good potential the price increases higher, I believe this is due to adoption Cryptocurrency is still in its early stages, so all possibilities are still possible in the future.

When going to trade, you must know the capacity you have, such as knowledge and experience.
If you are a beginner with little experience and knowledge then don't take too big a risk, even at this position you are better off not trading and it is better to spend your time studying first before trading with money.
But if you really want to trade, then the way to minimize your risk is to trade on coins that have a large market cap and are ranked in the top 10 in CMC, the reason is because coins that have a large market cap are very small to manipulate and the price movement is not too volatile, so you can minimize the losses that will occur when you predict the market wrong, but of course trade management will be your next key.

Binance doesn't really have a big community, Binance is big because it has BEP20 (BSC), without BSC Binance wouldn't have a big community and it's also impossible for the price of BNB to increase very high,
and also many projects see BSC because Ethereum gas is high, I'm sure when Ethereum gas is back to normal then all projects will return to the Ethereum network. I believe this is because Ethereum has a much larger ecosystem than Binance, which in essence is very difficult for Binance to replace Ethereum.

What you describe is a strategy of selling coins based on the period of holding the coin,
but the OP asked about how he sells when he has made a profit, I believe this is because he is worried that when he sells his coins the price goes up very high,
in this condition, usually I will sell some of the coins I have and move to other coins whose price has not gone up, so when the coins we hold go up very high we still hold some

Just like people in general, there is nothing wrong if Elon Musk invests in Dogecoin, only that the problem is the overreaction of his followers thus creating FOMO, and this is made worse because many stock players enter the cryptocurrency.
However, there is an interesting fact that recently happened, if you watch the video of The B World event, you will know that Elon Musk is not only investing in Dogecoin, but also in Bitcoin and Ethereum.

Overconfidence is one of the enemies of a trader, no matter novice or professional traders, usually this mistake arises because they feel that if the analysis is done correctly and has good knowledge,
in fact, the essence of trading is not like that, but about management and anticipation, knowledge alone is not enough if you do not understand management, this is because not all traders who have knowledge have good management, but traders who have good management are traders who have knowledge and experience.

Since shitcoin got a lot of attention I never touch such coin again, I didnt even buy dogecoin since 2020, DeFi or too similar name is already very suspicious ,
but for DeFi projects there are few exceptions, it's better to choose a project that has been around for a long time, and see if the project already has a product or not, DeFi projects without a product are bullshit, so make sure Product is the main reason if you want to invest in a DeFi project.
