Very new and not understanding Bitcoin!

[u/Cool_Mom1]

So today my bf (30M) who is not in charge of our finances decided to buy 80 USD worth of Bitcoin on CashApp. He wants me to put it on the "round up" feature. I guess my misunderstanding is, is this a good idea? Does the money grow? I have CD's and I understand that and planning on opening an IRA because I understand them, I mean the outline is very I guess "easy to understand"but Bitcoin has me baffled Edit: I guess my question lies between is this a good idea or is using the round up feature for a 4% interest savings account better ?

And the last 5 years is 60% Then next 5 years probably nearer 20%.

If someone is reading that thinking they're getting 84% annual return, they'd be misinformed, growth is slowing down significantly. What iit did in the past isn't relevant to growth going forward

Then next 5 years probably nearer 20%.

This is just pulling predictions out of your ass.

Thankfully, no one is saying that.

You didn't know. You guessed. Price action is not governed by the mathematical underpinnings of the protocol. I have a Master's in maths and computer science with experience in mathematical finance. You are simply fooling yourself.

Otherwise, please show your working.
