3 digits is a complete bargain, even $999 is still way underpriced.
buy 3 digit bitcoin while it lasts, it won't last forever.
People almost say the same thing because they strongly believe on Bitcoin. Let's accept the truth that all of us Bitcoin users do pray and hope that Bitcoin price would go high because as you said. We would all sure gain profits when that event happens in the future that's why buying today's price of btc still not a bad thing.
you are not expecting a miracle that you pray for a price rise. it is an investment and if you think it is possible that you make a profit then invest, otherwise just buying and praying will never make you any money!
