So, what precautions should someone have taken in early 2010 as to avoid having reverse issues?
early 2010
you know already there was no real exchanging of coin for funds until near-on mid 2010
most people were still doing faucet giveaways.
no one was spending $1k to buy/invest in bitcoin in 2009-2010, especially not via paypal for anything let alone bitcoin
everyone knows paypal is more for the garage sale trinkets(ebay) purchase amounts
your obsession with trying to get as much info about experiences of 2009-2010 to fill-in a certain story where you want to pretend you were an early investor of $1k bitcoin at 2009-early 2010 prices is going to be a waste of time no one would believe you and they will want proof in the form of you signing an address of a hoard of coins you 'supposedly' have
i know your game is to try to get info to sound convincing by telling a story of how you 'supposedly' obtained coin. but that story wont be sufficient to be your "proof"
generally by mid 2010 people were buying $10-$50, at a stretch $100 of bitcoin(from my own research)..
so please stop trying to play-out this silly $1000 of bitcoin scenario of 2009-early2010 prices. we all know you are just trying to gather info to pretend its then your (con-artist) experience
