Technology is my first choice.
Have you ever thought of buying Bitcoin in 2009, 2010 until 2014 ??
Bitcoin offers fast transactions without third parties, with Blockchain owned by Bitcoin, all transaction data will be stored safely, therefore Bitcoin is used first to pay for pizza and if we look more at technology than money, of course, you will buy Bitcoin from in 2009 and saved it for payment of future transactions, then without you realizing the price of Bitcoin continued to rise due to the high number of requests.
