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.
2017 is almost out, so we're getting 2.5 BTC in the first year and who knows what in the second year. Keep in mind that the tulip field is also real estate which is bound to have quite some value. Might even want to consider just selling it for more Bitcoin than #1 anytime before or after the first round of profits.
