It's certainly gambling if you just to pick a token off Binance at random, but the underlying technology and uses for the blockchains differs greatly. This is where an understanding of the different products moves into investment territory. They aren't just variants of the same.
ADA, DOT, MATIC and AVAX are all Proof Of Stake, rather than the high energy use Proof Of Work technology which is behind BTC.
See, you seemingly know what you're on about, and definitely know more than myself about crypto, so you doing it is fine, but to most, what you've written there, might as well be in binary. I'm not sure what you know about risk and reward investment though, having knowledge of both is probably not common, and most investors probably wouldn't be risking more than 5% of any investing portfolio on crypto.
The blockchain idea seems fine, and that will have use, at some point, guaranteed, although it's about 10-50 years early for me. But needless energy use to guess a random number and solve pointless calculations to be the next part of the chain is bonkers, there is just no way on earth that can continue. Even China have sussed this, and they're backwards. Even if energy was free, it could still be used in better ways, guessing random numbers should be last in line. This is seemingly how bitcoin is ran, and whilst bitcoin is number one, it is making a joke out of something which could, in the end, be good. It does need to get away from crime too, but that's another ball game.
I liked the idea of Etherium where it could be used for contracts, I could see how that could work in construction when you want to work for a client but you're unsure of their financial standing, but I don't know a great deal about it, and I'm not sure how that's linked to bitcoin. I wouldn't invest in it though, I think there are much less risky "gambles" with good gains.
The problem is there are guys that know 20x less than me, who have been putting money into this which has jacked up the price, and then other idiots have joined in at the jacked-up price. For every 1 guy that knows what he is on about, there are 10 guys who get lucky, and there's 100 who are going to get their a$$ tanned.
Doge is an actual pi$$ take, and look what's happened to that, it's laughable.
Musk can move the whole market, massively, with a tweet. He whinged about bitcoin and moved to doge, bitcoin took doge down with it, bonkers.
He's on thin ice doing that too. It's funny though, as his company (which is doing great things, and on the up) is also be largely overvalued, which again is fuelled by retail "investors" coming in and jacking up the price when they've no idea how to calculate share worth and company value, it's insanity.
