In 2011, you told your friend that there is a new thing called BTC, would you like to buy some? He would say, do you believe in this thing? I might as well buy Q coins.
In 2012, BTC rose to $20, which was 100 times higher. You told him that you wanted to buy some. He would say that it has risen 100 times and will soon become a bubble.
In 2015, BTC hit a new high for three consecutive years. He would say, don't listen to those people who lied to you, you are now buying at a high price.
In 2018, it broke 2 for the first time, and you said it is actually good now. He would say, how dare you buy a number of hundreds of thousands?
In 2020, when the new high breaks 7, he will say that one coin can buy a luxury car, and it will soon be broken.
In 2021, when the price of Bitcoin breaks 7 and falls back to 2, he will take the initiative to find you with gloating, and say, "See, I told you, this thing is completely finished."
In 2023, when it returns to 7, he will say, "Don't you still believe what I said?"
