If you come back to bitcoin in 5 years you most likely wont even be able to afford to buy 0.05 bitcoins. With the next halving in 2020 plus the gradual increase in price due to new adopters if youre leaving now you moght as well stay away because youll be kicking yourself.
Now 0.1 Bitcoin = $820 (I am from Asia)
1 Bitcoin = 109 Japanese yen or 6.3 Chinese Yuan or 67.30 Indian rupees or 14 Indonesian Rupiah
