I was new to bitcoin in 2017.  In late November 2017, I opened a Coinbase account and deposited about $150 worth using a bitcoin ATM.  After the ATM fee, I ended up with $130 worth of btc in Coinbase.  I never have withdrawn any btc and I have not deposited/received more.  I did however send $25 worth to a friend using "send" in Coinbase.  That is all.  

I want everything to be legal and legit.  Do I report this on taxes, even though I didn't cash out?  Technically, my btc did go up in value by about $50 between November and December 31st (although it's down since).  

Or do you only report when you withdraw/cashout?  Do I have to report money that I send to some address too?  

P.S.  Don't laugh, I know it's only a small amount compared to you big shots out there, but I am so careful with my legal records that I fret over mere dollars, lol.
