The housing price is correct, based on the
House Price Index. But don't make the mistake of thinking you can extrapolate historic data with certainty: Bitcoin's price development wasn't certain in 2016, and it's not certain now.
What you mean in short is that bitcoin is a speculative asset. I found that to be true but that is how life is because people are speculating on a lot of things including gold. With how the world is right now as they have embarrassed bitcoin, the price by the next 10 years is going to increase and another of this kind of posts will be posted at that time if this forum is existing.
And make sure people who want to start DCA-ing Bitcoin should invest in the right place i.e. non custodial wallet.
Most people use centralized exchange as a place to hold their coins because they think it's safe and cheaper, but if one day the exchange went bankrupt and they can't withdraw their money, they will lost all of their hard earned money.
High bitcoin withdrawal on the exchanges is a disadvantage. Lightning network for small amount is good while normal wallet for the huge amount is good.
