Hello Mr. Burgess,
While I came in here wondering if Paddy Power might pay out early on your original bet, you've now caught my attention with these offerings from Betfair.
Personally, I don't see Bitcoin falling below €1,000 at any stage this year. While I don't dispute the very high volatility, or the risk of panic setting in some day and Bitcoin's price dropping a few thousand euro in value (even more than we've seen in recent times), I have a feeling that it would be supported if it went anywhere near €1k in 2018 (if we were talking 2-3 years time, that may well be a different story though, as I believe that Bitcoin is going to get left behind by other cryptos over the next couple of years).
The €5k bet is an entirely different matter however and perhaps worth consideration (I know this comment illustrates that I've lost some confidence in Bitcoin, since I posted in the prediction thread a while back btw)
Will you be putting money with Betfair and if so, on one or both of the above bets?
