The oldest Bitcoin address that I found in my archives was generated May-27-2011. The price that day was $8.50.
What a memory lane. Anybody would regret not having bought at a time like that on the hindsight. Such is life and sometimes that's laced with, "Had I known." Just imagine what a $100 investment would've been worth today.
My friend contact me for crypto MLM token coin in 2017, They was giving per day 1% daily return of investment. Then after I studied on internet about crypto currency and found Mother Currency (Bitcoin). Price was around $1200 per bitcoin. I purchased my first 2 bitcoins @1248 USD rather then purchase MLM coin. I keep those coins and sell those first coins @11467 USD. It was great experience.
I also was bitten by the same MLM bug in 2017. That was in January and Bitcoin was still hovering around $700-$900. Good a thing I registered here immediately and have learnt quite a lot since then. 2017 was the golden era though I was still a greenhorn then and never truly understood how to make the best out of that era. Now, things have changed.
