Yes I agree with OP, if you don't have interest for Bitcoin it will be difficult for you to understand it, especially when your not the one investing in it,
Well, the interest should be there in the first place for someone to spend time and money to understand what bitcoin is.
Someone who doesn't have the encouragement and enthusiasm in learning what bitcon is. They are the people that will have hard time in understanding it.
But as soon as they see that the value fo it grows overtime, that's when they're going to decide that they should have invested on it and learned before anyone else does.
Yes, it will definitely be a slow process, especially for those who are not interested, it will take time to get interested. They will gradually learn from the environment and in the future, as they realize how the price of Bitcoin is increasing, they will develop a strong interest in Bitcoin. Those who are not trying to understand Bitcoin now will eventually try to understand Bitcoin and, by creating interest in Bitcoin, will invest. Those who value Bitcoin now will see huge profits in the future, while those who do not value it now will regret it in the future. Of course, this regret will create a kind of interest in them, and from this interest they will learn to value Bitcoin.
