I recommended my friend invest in Bitcoin in 2020.

He ridiculed me and said it was a scam and that I was throwing away money.

I did not argue with him and let him be.

Later, in 2021, Bitcoin appreciated greatly.

One day, my friend called me. He seemed regretful.

"Man, I really should have listened to you," he said.

I did not tell him "I told you so." I just told him not to worry.

However, every time I saw him, every time the price of Bitcoin rose to an all-time high, he would mention it.

It was rather awkward as he was angry with himself but not with me.

At last, he has invested some in Bitcoin. It was only a little bit. He asked if it was too late.

I told him that it was never too late. Just do not expect to get rich immediately.

He is new to this, and does not follow the prices daily as I once did.
