I prefer the security and anonymity of OTC and ATMs.

I learned my lesson with MtGox. Lost 50 coins. Never again.

When I acquire coins, they go straight into offline cold storage, mostly paper wallets, although I do keep a small amount (less than 5 coins) in a Trezor for convenience.

I don't ever want to expose my coins to the internet. I also resent nosiness. Anonymity is the cornerstone of freedom.

Yes, ATM fees are usually higher than exchange fees but when you consider the cost of transferring fiat currency and the total lack of anonymity of online exchanges, it's a small price to pay.

Whenever I have the chance to acquire coins for cash, anonymously, it's a bonus. I've met other Bitcoiners at meetups who I only know on a first name basis. I've also bought coins from storefront gold and coin dealers without divulging my name. They get their cash, I get my coins, no names required.
