im not Gyrsur but i mined btc back in 2011 onward and also buy/bought here and there over the years.
my answers are huge yes, big yes, and yes.
May I ask what is the percentage between total incoming BTC over that time and currently hodl'ed BTC is? Or maximum BTC hodled vs currently....
hard to tell. back when i started and btc was so cheap i didnt really pay attention. i got in it for the experimental aspect more than any profit. all i know is, aside from the first few years, every year i have less btc, but the real world value of that lessor amount of coins is more. usually much more.
as a miner you can look at it as dollar cost averaging, more or less. like i "buy" coin every week, non stop as long as i mine. then sell as needed.
ive mainly used btc as a kind of a "level up" thing. as in i mainly used them to "upgrade" stuff like vacations, toys, gifts etc to a higher level than i would of without btc. occasionally i would lock a chunk of profit up and put it into efts or other non crypto assets that (hopefully) earn returns in a more conventional, less risky way but of course with much less potential profit.
So it seems to appear that you are regularly taking profits in fiat and consumable goods, and you are not stacking aside bitcoin in a kind of fundamental view that bitcoin could potentially have more value some day.
I understand that you have been in bitcoin longer than me, but largely I have considered bitcoin as something to attempt to stack up, so if I spend BTC, then I attempt to replace the ones that I spent. I have been looser with myself regarding this in recent times, because I have established some ways to monitory my fiat versus BTC level, and created my own reasoned considerations regarding how many BTC that I want to maintain at certain price points, and if I have at least enough BTC to continue to reach that stacking BTC goal, then I don't mind shaving off a bit extra fiat for consumable goods.
