Face it, the reason that Bitcoin took off the way it has so far was because everyone could participate, profitably, with a minimal investment.
Ummm .... no, sorry. Profitability in mining is not "the reason that Bitcoin took off".

Bitcoin needs to stand up and be counted against Litecoin, ripple etc. Maybe we all sing only from the song sheet born from our vested interest, however if it's now impossible to state anything negative towards btc without being branded an altcoin sympathiser then it's impossible to have a reasonable discussion.

Modern miner Fat corporate cat in an ill fitting suit salivating with greed or valiant bitcoin soldier deffender of the blockchain?
