fyi: This topic is currently posted in "Altcoin Discussion", so I was expecting to discuss the way BTC Bull markets tend to effect Altcoin cycles. Let's do that? Historically, alt/BTC used to be strong when btc/usd fell fast ("correcting" from a rally) since the better alts where maintaining much of their USD value. However, once the "mania top" is in and BTC is extremely Bearish, then the alts take a severe hit since the frightened masses are selling their alts to also exit BTC ASAP.
Good news: On the Bullish "Big Rally" BTC side, making money with Alt/USD is easy, and sometimes you can also gain much more from Alt/BTC going up too.
