Yep.. there are many folks who are new to bitcoin, and they believe that they are learning "quality" information when they start fucking around with various shitcoins and also diluting the possibilities of their BTC investment in terms of time, energies and money invested.
Bitcoin is too boring for some of them.. grandpa coin, remember?
In the meantime, they get distracted into mostly valueless nonsense, and they don't even know what "grandpa coin" is. .They think that they know, but they have not spent enough time figuring out what they think that they know but that they do not know.
Frequently, I suggest for newbies to bitcoin to start with bitcoin first, and spend time accumulating it and perhaps learning about it. and if there has been a couple of years of BTC investment and accumulation then maybe there might be some need (perhaps?) to look into other matters.. and surely I understand the allure, too.. because what seems to happen is that various shitcoins, defi, NFTs, ICOs and other non-bitcoin crypto bullshit lure people away into thinking that their time, energies and money will be better spent on the 20,000 plus various non-bitcoin projects that again distract away from where the value should be focused (on bitcoin)..
....so those shit projects are lures, and if you dabble a little bit, you may end up getting sucked in.. like a slippery slope in which a little bit of looking into it likely ends up polluting your thinking into gobbledy-gook that lacks foundation and sufficient attachment to various realities - including that bitcoin builds on strong foundation, and surely there is a lot to learn, even with the lightning network, it should be possible to stay busy in bitcoin for 2-5 years at least before even feeling like you have a decent enough grasp on it that you might consider possible value in looking into shitcoins, too.
I just wonder how most of us really get fucked with shitcoins before we learn and deviate. Although some never get into the fucked up altcoin shit, really most of us got a taste of it (like myself).
Another thing that gets people tangled up with those fucked shitcoins is their price compared to the price of Bitcoin, which convinces them to think of accumulating 1 bitcoin as a nearly impossible venture (but very much possible); they just fail to realize that it does not possibly mean that one must accumulate 1 or 0.5 bitcoin at a stretch, but just like you said, despite how long it may take, 10 to 20 years of gradually accumulating Bitcoin is better off than getting deceived with mirror pump and dump nonsense🤣😅.
You said it all already: "if newbies can start investing first in Bitcoin and avoid shittie." It will be better for them. I don't see it as something they can't do, but they get so quickly convinced of how they can easily acquire a significant sum of some shitcoins from ICOs and IDOs, but they fear they can't get enough of Bitcoin, and they equally feel the profit for those shitcoins will be boom 🤯💥, not knowing that altcoin investment is just as risky as gambling.
My regret was that I also got fucked with some altcoins when I started doing crypto; back then, I felt Bitcoin was too expensive to buy while I could just buy thousands of some shitcoins. Perhaps it was because I only got introduced to a shitcoin whose name no longer exists.
Recently, I also took the risk of diving into a shitcoin, but I couldn't get out because right now, the token is dumped without trading volume.
