It is difficult to know what level of adoption bitcoin has, and I have my doubts that it has even reached 1% of the world's population, even though we have rich folks and rich institutions currently coming into bitcoin, including some of them entering through the newly approved Spot ETFs. These guys are neither imuned from gambling tendencies or making mistakes of the past, including but not limited to mistakes made that led up to a lot of the 2022 cascading crashes of Terra/Luna, Celsius, Blockfi, 3AC, Voyager, FTX, Alameda Research, Genesis (perhaps involving Grayscale) and probably some others that I am forgetting about...
Alts are launched with so many attractive features. They roam around for sometimes and then lost in the darkness forever. I had a crush on MATIC (POLYGON) last year after reading its features like side chains, low fees and more. The token is still there but wasn't able to take off despite so much marketing about its attractive features and now the team is launching new token with new features to generate more capital. The story may be different for other alts but the aim of all Alts are more or less same. There is no Alt that has survived the length of Bitcoin.
To be honest, altcoin projects do not offer any attractive features at all. They all always emphasize cheap transaction fees and fast transaction speeds, but other than that, I don't see anything outstanding that really deserves our attention. But if just to get cheap fees and fast transaction speed but lose the decentralized nature, do you need it? So if there are any altcoins that can create a blockchain with cheap transaction fees and fast speeds while retaining the decentralized nature of bitcoin then they will truly excel. Otherwise they are nothing worth our attention.
For me, altcoins used for speculation or gambling are more suitable. We can take advantage of our knowledge to speculate and should leave after making a profit. Don't believe any promises made by any altcoin.
