For me I would like to say for now Bitcoin is the only stable coin that can give you good life,
Bitcoin is not a stable coin please dont get it all wrong. It has only gain significant price over the years irrespective of its fluctuation and market volatility. And please stop referring Bitcoin to stablecoins. Stablecoins like USDT are fiat currencies pegged by a local currency. Anyway that's not the topic of discussion here i will leave you to make your research.
For me I would like to say for now Bitcoin is the only stable coin that can give you good life, except you don't know what to do, you said it does not guarantee you good life,
You are getting everything wrong here. Bitcoin does not guarantee that you good life in the future and it also doesn't meant if you dont invest in Bitcoin your life will be useless. I dont know where you are getting this reasoning from but whatever way it is very wrong. Most people invest in Bitcoin and still do it the wrong way while some invest and are successful. It all depends on the investor, of course Bitcoin has outperform most asset over the years in terms of longetivity benefits. And there is a high tendency that holding Bitcoin for decades will give more profit depending on what we have invested so far. Dont invest $10 and expect a million dollars.
