i remember that it was my entry point too as i started at $10 went to ~$30 then down to ~$2. and it stayed low for a looong time as i recall. and i kept just kept mining even at a loss at times.. but interestingly thats where the bulk of my stash is from, those early mining days when only the dedicated kept running gears. obviously it paid of handsomely.
so tldr version: keep stacking
If you entry point was $10 then you must be a Bitcoin whale by now

sure if i had never spent any. but the general rule the wife and i came up with was back in 2011 when mining 1/3 was to be for repayment of the mining card, 1/3 was to electric, and the last 1/3 was to be "saved."
however, i, like many other who mined cheap coins back in the day, sold a lot of those cheap coins back in the day,
so, whale? haha no. im more like plankton.
That reminds me of my bitcoin journey. My entry point was also ~$10 per btc.
I remember keeping 420 btc in my bitcoin core wallet, because as a stoner, that was a cool number.
F*ck if I knew. Mistakes has been made.
