Just like we easily underestimate a bull market, so do we do a bear market. So no reinvesting for me yet after only 1 month correction at valuations still as high as 3 months back ($400 billion), maybe after couple more months correction, when $3k BTC is hit, $200 billion overall market cap broken, and when optimism is gone, I will consider reinvesting for a possible 3th bull market in 2018 to new highs. Noticable that Bitcoin is not gaining market dominance in this bear, first time ever. Bull or Bear, Ethereum will likely become bigger than Bitcoin this year, transforming the "bitcoin market" into a "crypto market" for good. Bitcoin will lose it's priviliged position where people first invest into it before going to others, causing likely a continued slide in market dominance. On the other hand, Bitcoin Cash is continuing to gain adoption from merchants and companies that dropped Bitcoin due to it's high transaction fees. Also a word on the negativity of certain communities vs other communities and coins.
