Surf City is really a great resource for trading GBTC ( the bitcoin etf)

He is identifying the cycles in this instrument and applying Chartology and even Basic Elliot Wave

in an effort to trade the beast .

Surf has also done a lot of research on BitCoin and Crypto Currencies in General

Top notch analysis on a potentially life changing trade
