Buying Bitcoin is like planting trees. The best time to do it is 10 years ago. The second best time is today.
I agree with you, investment in BTC is like planting a tree and waiting for it to grow into a big one and you'll earn a fortune if you know when to the right time to harvest the fruit of your long-term holding. It's better to invest in BTC than saving money in a bank simply because of massive growth potential and of course, big loss should also consider when investing in BTC or other cryptocurrency coins.
