I absolutely agree with you. First of all, you need to rely on the technological map of the project, on its long-term perspective. After all, if the project is really applicable in the crypto space, then your investments are much less likely to be lost. We can take as an example several projects that can now change the idea of the Ethereum network (problems with transactions, their cost, speed and low scalability). Solana, Near Protocol, Matic. Their charts clearly show that they had moments of falling in the bear market, but users and investors did not let these projects get lost among altcoin garbage. All because these projects carry the right technological solutions
That's right but the real challenge is to find such coins before they are explored by everyone else. Once a coin is explored by everyone or has a mammoth ICO, it really becomes a dead ass coin, just like EOS.You can buy Ethereum during the dip, maybe BNB and even ADA but you cannot afford to buy meme coins during a dip in the market.
Altcoins trading isn't as simple as it might look to an outsider because there are scam coins, projects good but lack interest and then there are those who have potential, a good team but still can't get things going.
Just as I read your post I realized how I forgot about EOS. It is a rank 30 coin now. Didn't they collect an amount something like $4 billion?
As OP said the good coins survive the dip but that does by no means mean that the dip also is a real hit!
In the truest sense, alt coins suffer hard during dips no matter how good they performed and how good they actually are. Ethereum went so far down during the last major crash it went even under $100 again. But yes OP is right Ethereum survived and is doing awesome these days at least in terms of its price.
