The way I'm looking at next bullrun am thinking that the bullrun will be something that will push bitcoin price to approach hundreds thousands [100] for the price, but people will not invest now.
You haven't stopped to do the maths, as happens in many of these threads. To be a billionaire in the next bull run you will need to invest a lot more money than you think.
With the numbers you give, if you have $1,000 in bitcoin now, you will have $4,000 when the price reaches $100,000. Let's be optimistic and assume that the price next cycle doubles that amount, so you will have $8,000. To become a billionaire you would have to start with $125,000,000 and I don't think you have that.
Bitcoin can give you a good return but it is not going to change your life in one cycle. For something significant you are going to have to invest aggressively for a couple of cycles, but I recommend taking it easy, investing little by little and enjoying the process.
