How many people on here use bitcoin or other cryptocurrencies?

I known cryptocurrencies are something the CB is against as they want to keep fucking with the current fiat currency that's not even back by gold anymore. No matter what happens this year, I do wonder what all might change with money this year.

I like cash but now days probably prefer cards more out of convenience. I've never tried out any cryptocurrency. I always felt like if nothing can regulate it then what can stop criminals from fucking with it in bad ways.
