Can bitcoin somehow adapt DAG?
No. Bitcoiners are scared of changes.
It is not that we are scared of changes. I am eager to diversify some of my BTC portfolio, to make gains faster by getting into a project that is not smoke and mirrors/not a plain meme, the problem is, I can't find it. There is always something that makes me thing im investing into a short lived pump and dump, or medium term pump and dump at best if the project is something ambitious but ultimately has flaws that make it nonviable long term.
I don't feel like getting my hard earned BTC scammed by investing in altcoins that don't end up delivering anything relevant enough beyond what BTC can currently (or in the future) offer. And I work my ass off for a low paying job with bad health in order to invest in my BTC portfolio and continue growing it so that makes me extra cautious when investing a single satoshi.
You're experienced member and eberything you said is reasonable. I, personally, think that in long term Bitcoin will lose its crown and other cryptocurrency will take a lead. But this question is not about a
value but about a mass adoption. Bitcoin can sustain its value as a concept of
store of value but it is not suitable for everyday transactions. Byteball is revolutionary. I have bytes in my portforlio and doing very well. I also invested in RaiBlocks. It is a perfect micropayment system that, IMO, could overtake BTC in the so-called Third World.
