I am a shareholder in one of waldohoover's many groupbuys, it's a knc jupiter groupbuy. I had a problem with him increasing his fees from 3% originally to 7-8% AFTER miners arrived and started hashing. Also, I have bought a share in another groupbuy with tyrion and blastbob and they are professional and kept their word, excellent groupbuy admins, I mention them because tyrion&blastbob PAYS higher than waldohoover, exact same hashrate share in both of them, yet tyrion and blastbob pays out more btc every week than waldohoover. Needless to say, I am not a happy camper/shareholder in waldohoover's groupbuy. Oh yeah, one more thing, waldohoover's neighborhood lost power one morning and the miners didn't come back online for almost 4 days, even though power was restored the very same day. No one was reimbursed for the lost days.
Is waldohoover a good guy? I don't doubt for a second that he's a good guy. Will I do another groupbuy with him as the organizer? No way. Can you trust him? You can trust him like you can trust any random person on the Internet. Caveat Emptor.
