1) 3 BTC
2) Tulip fields
3) Emily Ratajkowski
Easy.
#1 because with my 3 BTC I will soon be able to do #2 and #3 (and be left with more than 2 BTC)...
#2 you get to buy 2.5 BTC which is only half a BTC short of #1 in the first year alone, which is just about to end. Going to end up with more Bitcoins with #2, especially if you reinvest.
Well, 2017 is out, tulip money will come after you sell them. By that time you will barely be able to buy 1 BTC with that money. The following year it will be 0.1 BTC, the one after that 0.01 BTC, ad infinitum. With option #2 you'll end up with exactly 1.111... BTC, according to my calculations.
