I think the key to this is patience, and not panicking when the price plummets.
I have a couple of hundred dollars worth of crypto - well I do now. A couple of week ago I had a couple of thousand dollars worth.
But I'm not bailing out just yet. If I sell up, i get not a lot. if I wait patiently, I either get less than not a lot, or I get a lot when the price goes up again.
The trend over the last few years, as far as I can see, is for crypto to crash at the beginning of the year and then build towards new highs at the end of the year.
So now is a good time to squirrel a little into crypto, and jut leave it there. And don't worry about what is happening day to day.
