Bitcoin is a long option to a better world with infinite maturity and zero time value.
If a better world comes, it will be so valuable.
If a worse world comes instead, I think it will also be very valuable

I am holding.
What happened to Monero?
I don't think it is the subject of this thread, but:
- Monero is a leveraged bet on Bitcoin, and
- A hedge on Bitcoin.
It is not prudent to invest a large part of your wealth in Monero, because the probability that it will completely fail next year is
at least 25%. The probability that Bitcoin will not see 2016 is
at max 5%. Monero has much better +EV though.
