If you can turn back the hands of time which crypto coin will you start mining? I had all the chances to become a big whale in crypto space today through mining, I even had a friend who want to give me 1 BTC in 2012 and I still turn him down saying it's nonsense, I had a lot of PCs laying around in that very year too but I couldn't mine a single BTC or any other altcoins until it's too late
