Right now on Preev.com 0.01 BTC is 297 USD. So you can easily see what that means if you own a 0.01 BTC, Price of BTC fluctuates and if it crosses 100k mark then 0.01 BTC will have some decent value. I would say there is no amount of bitcoin that can make you rich because we are not clear on what lies ahead. BTC is sometimes on 60k, sometimes on 29k.
Yes, it is difficult to say how much bitcoins we hold that will make us rich, because markets are unpredictable. But holding bitcoin is a good thing and we should do it regularly, collecting as much bitcoins as possible, Bitcoin may not make us millionaires, but bitcoin is a safe haven and a very good long-term investment. Those who hold bitcoin in the future at least have a life that is not too strenuous.
