You're dead wrong about btc losing top spot. I'm willing to lock away a few btc for a year... wanna get into a bet?
I dont think betting is childish nor would the millions of adult's who place bets daily. How about you call a casino in Vegas and ask them if they think betting is childish.
The fact you're even suggesting such a bet tells you're actually being childish.
- if I believe BTC will go down within a year, why would I want to accept BTC when I win?
- if I believe BTC will go down within a year, why would I want to lock it away when I should sell before it goes down?
- the amount of BTC locked away for a year can make a lot more than 2x returns in the volatile alt markets given you're suggesting evens.
