Except come tax time you need to declare your crypto..

Fortunately I live in a country where such thing is a big tabu. I only need to declare my gains (and only in case I'm holding less than a year) - and there are none if I am simply using BTC to send cash.

So btc has only gone down since you bought it?

If you buy btc, and value goes up, and you use it to "send cash" that is a gain.

BTC has stayed the same price for the duration of my transfers. It's just a few hours most of the time. There is also allowance in the law for this case - I don't need to declare anything unless I profit over $1k/year.

> for the duration of my transfers

What about for the duration of you keeping it in your wallet?

I buy it when I need to transfer (usually using a Bitcoin ATM) and then transfer it immediately - and sometimes I deposit it to the target wallet directly.
