Yes, people don't need to be rich before they can start investing in bitcoin, but they need a good income source that can cover their expenses so they can accumulate bitcoin without finding it hard to solve their unforeseen financial problems. This will allow them to hold their bitcoin for the expected year they want to sell it.

Exactly. Delaying their bitcoin journey, not knowing that if they miss this bull run, the next time they will find it will be 4 years after the next halving.

So many people are not aware of this, that the crypto market is divided into the bull run and the bearish market. The best time to invest in bitcoin is during the bearish market, and of bull run, have a selected price tag to sell some part of your bitcoin and hodl the rest because no one knows what the price of bitcoin will be in the future
