This is as if you are talking to me directly. It was real torture when I first bought Bitcoin after a friend convinced me to buy that I will make quick profit. As a student, it was not easy watching my investment down by almost 20% in few weeks. Well I am happy my friend was patient with me, giving me all the support and encouragement I needed then, so it took me time to begin to understand how the market works.
So now you can apply your own strategy when it's a good time to buy. That is an advantage that is not material but immaterial that cannot be touched but can be felt.
If assessed further from your experience, it's not the price of Bitcoin that is expensive but the opportunity to own Bitcoin is expensive.
It doesn't take long for what I want to say. Trying to own Bitcoin as an investment asset is a choice.
If you are sure of Bitcoin, buy it.
Not 20%, maybe you will get 50% profit and can be more than that.
