Regarding that 80K btc ($9.4 bil) guy/gal (most likely guy) sell...
Remember, he/she/they bought at $0.675/btc in 2011.
Two years (or about) later, btc went to $1176, which is a 1742X return in just two years (174222% exactly).
The will power that was needed not to sell back then...big respect.
Later on, fluctuations were less violent, so I can see how this (hodl) developed.
When I look at my bank balance 🏛️ I'm poor 🥴😥 Because it says: $800
When I look at my crypto balance 📈 wow im so rich 🤑 because I own "****" BTC
sure, if you own four digits worth of bitcoin, you ARE rich, lol
