How to Bet Agains Bitcoin Without Risk?
I thought about shorting bitcoin in bitfinex but i think there's risk of a margin call... (even if I don't use leverage the exchange could close my position right?)
basically I want to bet against bitcoin without risk for the next 5 years
is this possible? how?
Any kind of bet against Bitcoin involves risk.
If you sell, you risk having to buying back higher. If you short, that equates to dollar losses, not just bitcoin losses. And leverage carries the risk of margin calls. You need collateral to short, and just storing funds on BTC exchanges is risky: they are prone to hacks, exit scams, DDOS and API failure during volatility, etc.
The only kind of "no-risk" trades are arbitrage schemes. That means buying low at Exchange A, selling higher at Exchange B and sending the fiat back to Exchange A. Or you can arbitrage futures.
Here's a guide on how to do that. Arbitrage usually brings pretty low returns, though.
