Right now, Bitcoin is very unstable so it would probably take another 4-5 years to really see an impact on it. Maybe the next year would be better, but nobody knows if it will be because crypto is unpredictable. Only time will tell if Bitcoin's price would reach $1000 and mainstream adoption
Nothing to do $1000 and mainstream adoption. When bitcoin hit $1000 no one would be ready to spend it. Everyone will hold it for the price of $2000. So, Only after a very big price like one million dollar per one bitcoin, after holding that price for many years bitcoin may go for main stream adoption. Till that bitcoin would be a investment.
