Thats ridiculous. Very few "normal" guys can throw $70,000 USD onto what is still very much an extremely speculative investment. Maybe you're on wallstreet and think $70K is throw away money, but don't be confused. You have to be crazy well off to throw $70,000 into something as far out as bitcoin.
Probably I live in a country with a lot more money available for the average joe.
20 Bitcoins are worth 11-12k CHF -> most people with academic background earn that in 1-1.5 months!
Yes, I can tell you, 20-100 BTC are no problem to invest including portfolio diversification (bitcoin shouldn't be more then 10% of your savings -> high risk).
BTW. I'm a student and I have more then 20 BTCs..
@ seleme: how old are you?
Just check the salary in switzerland and stop complaining about your miserable income.
You live in a country where a shitty kebab costs ten euros, starbucks 7 euros, and a stay in a shitty hotel with beds worse than a third world country 100 euros. Have perspective, you do not.
