How would a reduced price "tank" his other business interests, considering most of these businesses will be set up to extract transaction fees which don't care about price, just usage.
I'm curious as to what bitcoin businesses this guy is even invested in. Googling the guy shows he bought a bunch of coins, plans to invest in some bitcoin businesses in the future (could be another pump line), and that he thinks it will go to 10k. No actual businesses listed anywhere, though.
From this link,
http://www.coindesk.com/bitcoin-venture-capital/, his fund has invested in:
-Coinplug - Second (10-14)
-Snapcard (10-14)
-Korbit - Second 8-14)
-Volabit (7-14)
-BitPagos (6-14)
-Vaurum (5-14) - Now Mirror, and this is the one he noted the auction coin would be used for, to add liquidity
