I received an email on the 29th of April 2012 from a close friend who basically said I should buy BTC.
They were $5 each.
Of course I regret not buying any.
That can be a huge pity. If you spent $ 100 to buy Bitcoin for $ 5 then now you have become a billionaire. I knew Bitcoin when it first started, but I did not invest in it. I really regret to ignore the opportunity to become billionaires
