Only took me 5 years to figure that out haha. But I never sold the BTC I bought at $900 when it was coming down from $1200 back in 2012. I'm still up 8x - better than anything short of Netflix and Amazon.
LoL, I had 2.5 BTC purely left over from mining in 2013/14. Then I sold 1 just before the BCH fork (there was a lot of scaremongering and risk involved... which prove to be all BS afterwards) so around $2500. The rest I sold further down the road on the way up... Must've been around $6000 iirc. Still pretty damn good trades when you think of it.
Now I stick to all BTC I produce with my rigs. Well, I'm mining, staking and keeping all the VEIL I can get with my nVidias, but all various proceeds from the Vega rig goes straight to BTC.
Glad I am not the only one that sold a bunch of BTC leading up to the BCH fork. Most people don't remember but people were freaking out that BTC blockchain will come to a halt because people will abandon it for the more profitable BCH chain.
In hindsight it would of been smart to hold all the BCH until that Coinbase launch where it hit $3000 but who knew it would happen.
I remember all the shennanagins with BCH how they got like 50 blocks in an hour due to the crappy early difficulty adjustment algo. And most miners kept switching back and forth and slowing down the BTC chain since it took a while for the difficulty to adjust. However even when mining wasn't profitable people still were loyal to BTC, crazy times. Feels like an eternity but it was only in Q4 2017. Time sure flies.
