I don't have an exit strategy. When the price goes down I just stand by, check the price from time to time and literally do nothing.

First of all, don't be like me. You should always have an exit strategy.

But I don't. I also actually never sold for any profit.

I came to the point where I would check prices of the coins I hold once in a week. And I would be like "aaahh, it is going down, I am already at loss...well guess I will have to wait".

And then I just wait and HODL.

It happened so many times to me that I lost that feeling of adrenaline when the price goes up or down.

I missed some good profits that way, but I don't have a crystal ball where I would see the future. Still, I see my mistakes and will try to learn on them.
