Think of it as investing in another currency.

Just remember, never invest more than you can afford to lose, and quit while you're ahead.

Investing in dollar? wow, very good idea. (sarcasm)

Trust me. $1 will never be equal to even $1.1 Grin

But
1BTC ~~has a great chance to be at around $600.~~ will never be equal to even 1.1BTC

FTFY because consistency

Those who sold BTC/bought USD have been pointing fingers and laughing at you for over a year now.
