I'm thinking of migrating over to Binance. I presume their charts are pretty true to the real value of BTC; with it's high liquidity and not having margin trading?
Ah, one more thing to consider. Bitfinex sometimes has banking problems. This inflates crypto prices on the exchange since people can only buy crypto to withdraw. You can see BTC is trading $120 higher on Bitfinex than the rest of the market right now. This can be another source of volatility/unpredictability. Check the price action on October 14th for example: that big spike was banking FUD.
I mention this because Binance only offers stablecoin markets for "fiat" trading, the biggest markets being USDT. USDT mirrors Bitfinex prices because Bitfinex and Tether are owned and operated by the same company. Bitfinex is the only place where Tether is redeemed at 1:1 to USD.
So that's one more thing to consider. Many traders consider the prices at true spot exchanges like Coinbase and Bitstamp to be the most reliable.
