I knew about bitcoin, but had never invested in it until 2015.

My marriage was falling apart.  My wife and I were legally separated, and I knew that divorce was inevitable.

I started salting away a little out of each paycheck into BTC, and later, into ETH also.

Needless to say, those little investments have paid off in a big way.  I have more money in crypto than I have in my stock trading account, which (outside of retirement accounts) is the bulk of my life savings.
I am much better off financially than before the divorce.

Bitcoin has been life-changing in a very positive way.
