I bought my first BTC back in 2018, and still worried about losing it until now

Holding BTC (other crypto as well) for the long term is not only an experience of staying for profit but also staying in worry.

I have to consider multiple tools and platforms in order to spread risk, and end up bearing management burden and maintenance costs. Meanwhile I have to keep an eye all the time, which is not the case for my fiat money.

Anyone feeling the same pain?
